- In this video I show you an easy way to show that light is neither a wave nor a particle (or it is both?) by doing the double slit experiment followed by an analog of the photoelectric effect. This is a crazy experiment that shows how weird quantum mechanics really is. And an added bonus is that you can do these experiments at home! Finally I even show you what an electron orbital really means.

I never realized that the split could be done on a low budget. That's cool!
This whole channel is the most info for the lowest cost to make. Not an insult at all.
It even featured “Da Vacuum Box”..as a table.
Use a laser and a straight pin.
Actually it isn't the real double slit experiment, but the results are still the same. The original experiment shoots one particle at a time, which splits at the double slit and afterwards interacts with it self and is measerued at the backplate. If we repeat this for a while we see the interferance pattern, whose amplitude corresponds to the probabilty of the particle beeing measured at this point. Only by shooting one particle at a time but still getting the interference pattern, you can proof that light is both a particle and a wave. If it wasn't a wave we would have no interference and would end up with two slits at the backplate (when repeating the experiment).
Also the interference pattern does not exist when we measure through which slit the particle went. Simplified, measuring means physically poking the wave which collapses it to a particle again, so no interference and we end up with the two slit pattern again.
I think it can be done with the sunlight as well. This is how it was done in the first place, as they had no lasers back then ;) Veritasium has a video with a large cardboard box. The sunlight, however, produces the pattern in multiple colours.
Back in 2005 I successfully replicated the double slit experiment using a laser as well and found out for myself how cool physics and reality really are...
I love this channel. It's so underrated. No fancy graphics or animations. You cut through all the gunk with simple and clear explanations.

You basically explained quantum mechanics in a simple way it's amazing.
Why does quantum mechanics feel like intuition.
@@Zimrack What do you mean by Intuition?
Great explanation. Love your videos. But here, a little mistake slipped in at 1:20:
In order for the double slit experiment to work, you don't need plane waves. It also works with curved waves in the same way. The reason why it doesn't work with a light bulb is the low spatial coherence of the light in this case (which is an entirely different beast than curvature). It basically means, that because the light bulb is an extended light source, the light waves incident on the slit are coming from many directions at the same time. So they create many of these interference patterns which are mutually shifted and therefore wash each other out. Fun fact: If you place the light bulb very far away from the slit, it would in fact give you an interference pattern also in this case (with very low intensity though).
I feel like you are getting ignored
Thank you for the clarification.
I think its obvious once you understeand the concept which I think he explained perfectly.
The Action Fail
Suga4all, good to know. Did you notice the red light created a bulb-dimensional affect? And the blue light made a strict wall with ability to make a shadow immediately in front. Meaning, red moved away and caused a round bulge going away from us and blue caused a coming towards us with a flat wall shadow. The Red light was a real good for NOTHING liar. The blue was honest and real. So, red light makes for time and distance, a lie. Blue makes for what "is", truly. This is why the farthest thing we perceive in distance away from us is actually what is closest to us.
People are particles, but when you put them together, they act like waves
that's a cool way of thinking about it
that alone isnt actually correct. even in experiments with individual photons they act like waves, interferring with themselves. same is true for other particles. its the propability that takes the waveform regardless of the number of particles.
@@94Newbie true. But he was talking about people, and if you think about it, he's right haha. But yeah you're correct

It is interesting already 😋
Nope physics is not interesting without this video bro
If only the double slit was to be made with blue light, perhaps we would see it painting it wide spread
You should do the last experiment with blue light.
yuupzee

Yes, i just wanted to write the same thing 😁
Ummm why is that?
“Then after you’re thoroughly confused, I’ll explain what light really is.”
I’ve never related more to anything in my life
I wish I were born in a simpler universe where light would be either particle or wave.
It is a coaxial circuit
ok than u should head to hell.. otherwise rest of the universe is more complex as we know till now about it ...
@@NetaNagarie How?
You are in a universe where light is neither a particle nor a wave. Light is a coaxial circuit made up of rarefactions and compressions of longitudinal dielectric pulses and necessitated electromagnetic divergent fronts from the compressions and rarefactions. Do not be sucked into the idiotic belief taught to us of the dual nature of light.

Someone here said your channel is underrated and I think that's probably true. You are doing a really great job explaining complicated science topics in an interesting way. My 8 year old son and I have been watching them during dinner for the last few days and we are both really enjoying them. My son usually only gets excited about basketball games or dude perfect but I can see him getting excited about what you are doing.

@@goddammitalana Just a small update. My son just got into the AP math program. Scored 99 percentile on CogAT.

Why didn’t you:
Use the BLUE light with the make-shift double slit on the glow paint? Would we have seen an interference pattern? Particle like result? Both?
We will never know.
it would be like the lightbulb
@@l-l-l-l-l-l-l-l-l Like the blue flashlight. Not the red bulb.
He did
@@sealofapoorval7437
Not through the double slit
Making interference pattern with the blue light is not easy because its wavelength is short. I guess he failed to make it at home. And it would lit the glow paint in the shape of the interference pattern.
So approachable and down to earth yet passes on so much knowledge. I love the genuine excitement. give this guy a laser pointer and a sharpie and some space in his garage and he makes me feel like I am learning more than I did in uni! yo PBS or TVO or BBC or someone get this guy a show!
So basically: Schroedinger's light.
this is the experiment that started the quamtum physics
Does that mean red light wont charge a glow in dark area
@@sbravoo that was the move that made scientists cry
@@Palladiumavoid yeah lol
well... I mean yeah, kinda, not really though. the cat thought experiment Schrödinger proposed was meant as a way to explain just how weird quantum phenomena is. he was trying to get across the idea to the general populace how it makes no sense that light (and indeed any particle) should behave both as a wave and a particle simultaneously. normally waves are nothing but the transmission of energy through a media (such as the ocean), the particles themselves shouldn't travel as waves yet thats what we see from these experiments. it is a problem that perplexes physicists to this day. The Schrödinger's cat thought experiment was explaining this very idea so it makes it a bit weird to take it and rebrand it as "Schrödinger's light".
This video really made my whole day. :)
The best part is explaining such topics with simple, easy and fun experiments.
You are doing a great job.

@The Action Lab, the experiment you do around 7 minutes in, isn't the fact that you used a *red* laser but an LED flashlight (which emits blue light, especially since that appears to be one with a higher color temperature) a big confound? You had already established the red light won't charge the glow in the dark surface, and that blue light will, so it seems hard to draw any conclusions about the quantized vs wavelike properties of light from that demonstration alone.
brandon i lietrally came to same conclusion... a blue laser would have resolved the issue much more clearly
Came to the comments to say this!
Light has the properties of a quantized wave: neither wave nor particle, neither fish nor fowl. The particle characterization of EMR has been superseded by quantum field theory. You don't need to invoke particles with momentum to explain a transfer of energy from photons to electrons. None the less, your double slit setup with the laser pointer is fun to see.
wow, that just explained to me how the electron orbitals work better than my chemistry teacher could in a decade xD (seriously, i`ve never really understood how orbitals work but now i do). Thanks for all of that science input, you can explain it like nobody else could
rubi_style Well i was astonished too! I used to think electrons follow just a single path orbiting the nucleus.
wtf? looking into wikipedia would fix ur problem in 1 minute...
What an excellent presentation. Thanks for putting this on here. It's so cleverly explained.
The best explanation of the particle-wave duality I have seen on youtube. Bravo.
I wish there were a better(easier)way to explain the delayed choice quantum eraser experiment. Great job on this video!! Keep it up!
My favorite experiment:)
kelan andersson so it is as confusing as I originally thought!! Thanks for the link, I liked it.
The Action Lab, wanna see the wave function?? I have a bunch of experiments showing it. Also got the electrons probability cloud nailed down.
At 7:00 you are using a red laser for the double slit. Try it with the blue laser.
But the point was to show that an extremely high amplitude light still cannot charge it. Which means that light cannot be purely classical waves. Blue light still would have charged it so it wouldn’t have displayed that effect.
The Action Lab
But red laser doesn't have a small amplitude so it won't make a difference if went through a double slit
RED light has wavelength around 700 nm and BLUE light around 400nm. (Momentum) P is inversely proportional to λ (wavelength). P = h/λ. Amplitude does not affect the momentum or the energy of a light wave. so it proves just that blue has higher energy than red. I looked up some specs for fluorescent materials, idk if its true fore every material but at least gives an idea.
you can find more here:
en.wikipedia.org/wiki/Electromagnetic_spectrum
www.celestialescapes.com/how-to-charge-your-glow-in-the-dark-gift.html
HEY did you study Einstein theory on Photoelectric Effect..... it depends on FREQUENCY not AMPLITUDE.... don't teach something wrong to guys here~~
The Action Lab
Great video. And it'd be great to see the lit charged with a blue laser (and a blue laser with interference)...just for completeness.
So light is a wavicle
Something I've been thinking about for a few days is what would happen if you shoot the interference pattern through a prism. Be it a pyramid or cube, I was wondering if that would give a view of the "wave like" property through "space" of the beam as opposed to just having it hit an opaque surface. (Basically like ballistic gelatin for light)
I hope this endeavor works out for you. I have yet to watch a single boring video from you. You are one of the few that gets a guaranteed slot in my limited "watch stuff" time :-)
Nerys yea I never got bored of his vids 👌👌

That was very articulate. Not everyone can explain the two slit and particular properties of light in a way that makes sense.
I can tell you enjoy teaching

Simply light and other particles are in superposition so it isn't a wave or particle but its still both before you messure it
Correct:)
Now tell me how to define a measurement:)
The Action Lab hey is saying that as the light particles r micro particle so we cannot track it or see it under even electron microscope... It moves before we see it
The Action Lab hey could you cover how our reality maybe a simulation in some kind of computer plz. This may explain why the quantum world behaves the way it does
Torille?
You are great; thank you for showing the experiments and the theory behind them separately.
This was a great video! Understood this concept better with this video than any other explanation in the past. Wonder if you could try the wave particle experiment with the blue light too next time.
Yes, that was a big missed opportunity.
You just explained my 10th grades lessons in 11 minutes... and I actually understood it this time.
Isn't the laser pointer a red light you said that red light cant light up the lit
Kyle Vardy I don’t understand either.. every club that I’ve ever been to that was totalllllly Liiiiiit!!!! Was full of red lights and red lazers.. are u telling me if thoze lights were blue my boogie nightz would have been even more Lit??? Because I don’t think that’s possible.. bcoz I get like.. suuuper Lit..
Yea Kyle your right
And it didn't
I was thinking about it all the fucking time.
only because it behaves like particle
if it would behave like a wave it could charge the lit
doesnt matter what colour
Came in expecting to learn about light, ended up learning about quantum mechanics. Great content!
Amazing explanation with such a simple experiment. Thank you!!!
first you confuse us by telling us something that we never almost talked about and then clear everything out
you are great
Nice and very informative
Love the hard work you put into each video mate
this is my first time seeing the double slit experiment in actual. thank you!
Absurdly inexpensive experiment for the magnitude of information conveyed. :)

Titles like these blow my mind into pieces
Bassel Dahdouh your mind is made up of over a trillion cells!
Hey Action Lab, you always have interesting experiments, usually in some area I am investigating! Thanks.
I have studied the light 'wave-particle' duality for a long time and I have concluded light is a wave with some particle-like properties.
Specifically, light is the vibration of the ether which is most likely the neutrinos that pervade the entire universe. This is the 'quantum fabric' that makes up space and is the stuff that vibrates to make light. Light acts like a particle when a wave of the quantum fabric finds a particle that can absorb it and that wave collapses instantly into a localized energy transfer.
The instantaneous behavior of light is confirmed in the fact that light has no inertia - it moves at its top speed instantly (from zero to 300,000 in 0 sec.) and it stops just as quickly. This instantaneous behavior is also confirmed by experiments showing quantum entanglement.
Light is also confirmed as a wave because the energy of light is determined by its frequency, not its mass or velocity.
The failure of modern physics to admit an ether makes the universe appear irrational. I have heard that the Michelson-Morley experiment has been overturned, and a drag component has been detected in light when the experiment is done with more precise instruments.
The quantum fabric is also the stuff that rotates to make a magnetic field and is the source of fields in general, with attractive and repulsive properties, depending on the particle and / or direction of rotation while interacting with the field.
These fields include the electric field, the magnetic field, the weak nuclear force and the strong nuclear force fields. Each field is determined by a frequency interacting with a particle and each one drops off by a particular inverse exponential - 2, 3, 4 or 5, respectively.
Thanks for that great explanation Mark! Saves me a lot of pondering. Lol!
Spectacular job of demonstrating and explaining that thorny issue.
Nice and informative video there, great job!!

Loved it. It's like an eye opener
Ur experiments makes it easy to understand topics. Good work
Nice video, but you were a bit off-base when you started talking about the momenta of photons in the phosphorescence of the glow in the dark paint. Light having momentum isn't really relevant to that particular phenomenon. That comes into play when you talk about things like Compton scattering (particles being deflected by light) or the photoelectric effect (electrons being ejected from atoms by light).
Your explanation is mostly correct and I don't mean to be pedantic, but these demonstrations are about energy, not momentum, and you should not use the two terms interchangeably.
The reason phosphorescence cannot be explained by the wave model is, as you say, the energy carried by a wave is related only to its amplitude. Thus, an intense beam of red light can have more energy in total than a dim beam of blue light. However, no matter how intense the red light, it cannot excite the atoms in the paint. This tells us that there are particles within the beam of light which interact with the electrons individually that these particles of light must have the correct amount of energy to interact with the electrons in the paint or the electrons will not be excited, and that the energy of each particle of light is different for different wavelengths of light.
That said I always enjoy your videos and there are a few I show in my classes every year. Keep up the good work.
SirPhysics - is it similar to a narrow band pass filter?
They're related in the sense that both have to do with the specific energies of light which can be absorbed by a material. All materials have different ranges of the spectrum which they will not interact with, and other ranges that they will. Glass for example, is (mostly) transparent to visible light because the energies of those frequencies of light do not correspond to any available energy level transitions or vibrational modes within the glass, but at the same time is completely opaque to infrared light. You can say the same thing about your skin; it is opaque to visible light but transparent to something like x-rays. Whether light passes through or is absorbed by a material comes down to the available energy levels in the atoms or molecules of that material and how they compare to the energy carried by photons of different "colors" of light.
I figured it was wavelength of the light having different effects on the material due to the peaks and valleys hitting the electrons at different speeds. Red wavelength might hit them head on and pass through, but that's not enough momentum to get them into the excited state; blue wavelength would slap into them sideways, the speed between it being at its peak and valley being much higher, and imparting more energy than being hit head on. I mean, red and blue light both move at C in a vacuum, but the blue wave is covering more ground and has to be moving "faster" to maintain the same forward speed. Like two cars swerving between pylons, the red one is weaving gently between pylons that are like, 20 meters apart, the blue one is swerving every 3 meters, but they stay head to head. The blue car would be much more energetic. /never studied physics
@@coyotecom yeah you're wrong. If two particles are travelling at the same speed, they would cover the same amount of ground in the same amount of time.
Momentum is correct. The energy of any particle (including photons) can be expressed as a multiple of planck's constant and the momentum.
It is possible to make that "Lit paint" glow when flashed with an ordinary commercial green light laser pointer??? If so, could you make a glowing interference pattern???
that was so helpful and time saving. gracias

Ok today i'm going to put a huge like
Tobi 👍
When I took physics in college my prof taught us about light being both wave and particle. I have puzzled over this since then (mid-1970s) But you said something that tied it together when you showed that it isn't just light, it is everything else too! Now I have even MORE to puzzle over! :)
Now, when you feel good about yourself, take a look at QFT - Quantum Field Theory ;)
The more questions you answer the more question you will have
I've seen many of your videos but this video made me subscribe your channel. Good job man👍🏼
It's amazing. Finaly i got it. A provability of locatiin an eletron and not the exact location. very well put.
I'm confused by one thing: would the double slit laser make the paint glow if a blue laser was used? I thought red light couldn't make the paint glow at all
James Geary
yes it would make the paint glow but he showed us about the red light because even though red light has higher amplitude, what we need to make the paint glow is higher momentum of the particles and not the amplitude!!
In other words, his experiment made no sense and invalidates his claim. @@amaankadri9173
Maybe light is particles which move in waveforms 🤔
WATCHING IT PRACTICALLY WAS AWESOME. THANK YOU 😊👍👍
Really appreciate this video. Thank you.
I'm wondering if the color of the wave is pertinent? The laser you used was red, try a blue one. Also, how about shining both types of light, white incandescent and white colored laser through prism onto that sheet to see if what colors are absorbed. Might be pretty interesting. Love your show!
There's no such thing as a white laser. And in fact, lightbulbs don't produce pure white light either. They are tricking your eye.
Exactly. This is bunk.
Great video. A question that I find never explained in any double slit video - if we fire single particles at the slits surely we aim them at the central block rather than at one slit or other right? If so then the expectation should be no pattern at all as should hit the central block. However actually goes through one or other slit, this must mean the single particle is bending its path once decides which slit to go through. Surely it is just as amazing that the particle decides to veer off a straight line as the overall result of the pattern made?
A single photon goes through both slits somehow (refraction?) and winds up as a single photon again when it hits the paper. You STILL wind up with an interference pattern after many single photons are fired. If you try to measure which slit it goes through, then it goes through only 1 slit, and you lose the interference pattern. If you try to measure which slit it goes through *after* it passes the slits but before it hits the paper, you still lose the interference pattern. So it's like the light "knows" you are about to measure it and picks one of the slits, even before it reaches your measurement device.
@@Hyxtryx thanks well said, yes I know what you say. My point is subtly different and never explained by any videos. A double slit by definition has a central barrier. Also to be a fair experiment you must aim your single photon at the central barrier, else you are automatically giving the photon a known path of one slit or the other. So the photon comes to the slit and it must 'see' a big barrier, so either it carries on and goes straight through the barrier missing all the atoms in its way or goes through one or both slits. But to do so it must have not travelled a straight path ie must have bent towards one or other or split into 2 and went through both and reformed.
Maybe they do split eg have 2 joined halves then reform after, just a guess. But we need to be able to explain the phenomenon BOTH on a particle basis and a wave basis.
Thank you for your great explanation!
very well made to explain the difference. Please keep up the good job
You don't even need the laser. I did the double-slit with my students using a sharp knife, a piece of thin cardboard, and the the flash light on their phones.
When I had studied this topic at first time I was not able to feel this and I had started to ignore it, but after seeing this video,I can say only one word that is wow😱
thank you for this fascinating and well explained video. I still don't quite understand quantum physics but also feel I'm getting closer to understanding it
Thankyou for this amazing video❤️
"Light cannot be anything else but a longitudinal disturbance in the ether, involving alternate compressions and rarefactions. In other words, light can be nothing else than a sound wave in the ether." - Nikola Tesla.
No bulb emits light waves just like a person in the middle of the pond moving his hands in water is not emitting any water waves. Light is the ether itself under vibration. And if there are particles of light, they are particles of ether acting very much like how air acts for sound waves.
Good old Ken
What a weird confusing sentence from the most intelligent scientist and the one who successfully made electricity usable in everyday life!
I agree! Light is just waves. Not sure if longitudinal or transversal. I would suspect transverse(even though tesla said otherwise..)
Saying light is a particle just because certain frequencies act diferantly is the stupidest justification I have ever heard of.
Example.. I think sound is a particle because some frequencies can brake glass...

Thanks you for the amazing video brother!
You are awesome on a high level.
Can you please try doing the same experiment...but this time, put an observer or indicator or camera which will collapse the wave function of the light... It will be fun to watch what happens with the lit paint :)
Delayed choice quantum eraser experiment.☺
The observer is anything in an open system that interacts with the closed quantum system. ...So the paper counts as the 'observer'.
(You just want more videos, don't you? ;)
"Observer" doesn't mean what you think it means. It's not "something looking at it", it's literally anything interacting with it.
One error:
_"Light is a wave therefore it is everywhere"_ is false, because light is an electromagnetic wave that has an origin point and a direction and a velocity. An electromagnetic wave moves through space from point A to point B over a specific duration defined by its velocity.
How odd. I'd say it's a 'rate of induction' as opposed to a velocity.
@@choke666 An electromagnetic wave is not induced while it travels.
According to quantum electrodynamics, a photon is the smallest possible unit of vibration in the quantized electromagnetic field which does not have a well defined trajectory because of quantum uncertainty, ie. the energy packets of EM fields are not localized untill they are absorbed somewhere and only then you can say "a photon traveled from point A to point B" but this does not contain any information about the route of the photon. Look up Feynman path integrals.
Was not an error, but a way of saying...linked to the context of the explanation.
Sound waves are the tubes and the particles travel through for example if we can make a lone sound wave we can put particles inside the tube
Thanks for the explanation.
Thank you sir 👍👍👍
Very well explained with examples and practical.....
I want to learn still more
