perfect explanation,the most curious thing i learned is that you done in theatre closing one eye.i will also try that one next time in the theatre .thanks!!!!!
Your explanation, the model of sliding perpendicular E fields, and the demonstrations REALLY helped me understand. ChatGPT's explanation alone wasn't clear enough for me.
cool. thanks for the explanation! the animation you had on your cell phone was more informative than the red ribbon in terms of explanation the vector sum. but there were a lot of other cool explanations in this video. especially the movie theater glasses.
The sound wave has two types: compress-wave(P-wave) and shear-wave(S-wave); P-Wave means medium particles oscillate along the propagating direction; S-wave represents particles oscillating perpendicular to the propagating direction. It seems that sound is "polarized", but we do not sense it: because we can only hear P-wave. (S-wave cannot travel through fluid, e.g. air, water, ...)
I wish this video was twice as long and had gone into twice as much detail about circular polarization and how exactly one of the light components is slowed down by a quarter phase. But I appreciate the explanation.
1. Is a linear polarizer defined by the electric or magnetic field, and is it defined by what it transmits or what it blocks? (a green color filter looks pink, for example) 2. where can i find more elaboration about the physics of the circular filter itself? 3. What experiments can I do to correctly define the polarity of light (or the filter) that I have? Am I looking at a vertical electric field? Is the electric field that bounces off a plane perpendicular or parallel to the plane?
1. Don't confuse a colour filter for a polarising filter. Colour filters work by absorbing a CERTAIN WAVELENGTH of light: if it absorbs blue and you shine white light through it, what you will see is the white light minus the blue light = red. Polarising filters slow down / attenuate light of ALL WAVELENGTHS: they just need to be travelling in a PLANE specific to the PLANE of the polarising filter 2. I'm sure you can find loads on the internet (sorry but google can answer that one) 3. a) He already answered this in the video b) The light has a net sum vector in a certain direction: but rotating the polarising filter you can see which direction that is c) Not sure what you mean by this.
Your model of a wave is very good. The moment you switched it to the circular polarized wave was like boom and suddenly it made sense to me why the iPhone display did not turn black. It is because the circular polarized light always has an amplitude isn't it? I mean the function has no roots. Am I correct with this?
yeahhhahahahahaha that's amazing. it's always exciting for me to wonder and see how the effects observable to us can be transmitted to the camera (and by extension, to other corresponding devices too)
I’ve come to realize that I’m not necessarily stupid, I’ve just had terrible teachers. Complex topics only seem like such because the people teaching them to me don’t fully grasp what they’re speaking of. Most proficient practitioners don’t become teachers. The key to intelligence is finding the right teachers. A good teacher makes a worlds difference.
"My left ear....." - it was so interesting that I didn't even notice that is was shifted to the left. Someone look for a content and someone to find what's wrong.
I think that linear polarizers also block out a gradation of light up to a 45-degree angle. Light waves are not oriented horizontally and vertically, perpendicular to their direction of travel. If it were orientated in such a way, you would get light seepage when you spun your stack of polarizers around at different angles. And that's not all. They also block shear in a gradation up to a 45-degree angle as light travels omni directionally.
Thankyou so much for this very nice video first, for a long time i am looking for what is that at the 4:05 your right hand take down for the 3D glasses, I am really want to know where can buy that plastic (that looks no color one) , cause i am want to make the Circular Polarization. thankyou again !
Regarding the experiment with the mirror and 3-D glasses, that demonstration is misleading in my opinion and needs to be clarified. It's true that if the experiment is done with 3-D glasses that are circularly polarized, then the lens over the open eye will appear darker in the image reflected from the mirror than the lens over the closed eye. However, if linearly polarized 3-D glasses are used, then the lens over the closed eye will appear to be darker in the reflected image. I think he should have mentioned that in BOTH cases one eye will appear darker and the only way to distinguish the linearly polarized glasses from the circularly polarized glasses is to pay attention to which eye looks darker. In my opinion, people who have not done this experiment with both types of 3-D glasses will come away from this demonstration thinking that one lens will only look darker in the mirror if circularly polarized glasses are used and that is not true.
Light is an electromagnetic wave. Its just that the electric part of light is made of two components which on average makes up the direction of the polarised light. The reason why we ignore the magnetic part is because we know it's perpendicular to the vector sum of the electric part. Or so I assume based on this video.
There are x and y components of the e field but are there also x and y components of the b field, it's net force perpendicular to the e field's net force?
As you are clearly the Chevy Chase of science, I hope you begin to include complimentary pratfalls in each video...thank you in advance...(and excellent video)
my left ear is thankful for this video!
oh good, my earphones aren't broken
:D
Unfortunately, my left side of my headphones don't work :(.
And my right😂
@@ammarraza1956 due to overuse, I hear less by a factor
That's brilliant. A not so intuitive phenomenon explained with such simplicity.
Finally a video that makes sense of this phenomenon, and doesn't just say 'it's another type of polarisation'.
The connect the string analogy really helped me wrap my head around the vector motion, thanks!
I love it! Explained in such an easy way!
Great presentation. Informative and interesting. Some subtle humour appreciated! Thanks.
Bro you explained literally everything I wanted to know AND in a way that allows me to understand how to use them effectively. Thank you so much.
I particularly like the sliding white E cardboard wave to show 90 deg. phase shift. Well done!
Most professional video lesson I have ever seen on polarization wave shape!
That was one nice presentation !! Congrats for the good work !!!
Absolutely brilliant!
Best explanation online! Thank you one million times
simple explanation, great visual. u the man
Woow ......
Just amazing......
❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
excellent demonstration you make to understand the polarization ..thanx
perfect explanation,the most curious thing i learned is that you done in theatre closing one eye.i will also try that one next time in the theatre
.thanks!!!!!
You're so weird I love it!! Keep the vids coming
That was absolutely awesome! thank you!
Wow, very impressive explanation.
IDEAL presentation!
This would be one of best explanations ever. Thanks professor.
Best explaination yet 👌👌
Wow Amazing video ever... I like it
i like the video how he asks question how we r sure than shows it. Making it a perfect blend of curiosity followed by solution
WoW, Saved a Ton of reading with this brilliant video
Great video
Your explanation, the model of sliding perpendicular E fields, and the demonstrations REALLY helped me understand. ChatGPT's explanation alone wasn't clear enough for me.
Explained so well!
i love it a lot.... fantastic
cool. thanks for the explanation! the animation you had on your cell phone was more informative than the red ribbon in terms of explanation the vector sum. but there were a lot of other cool explanations in this video. especially the movie theater glasses.
great effort....
original way of explanation
Very educational. Very interesting.
Thanks buddy for ur nice explanation with ur demonstration 👍👍👍keep it up
Brilliantly explained!
THis video answered so many questions I didn't even know I didn't know I had! Thanks!
Came here primarily to learn more about the circularly polarized 5.8GHz FPV camera systems work, but wanted to know about that in general.
Great informative video. Was the sound for it polarized as well? My left ear is receiving one component only ;)
The sound wave has two types: compress-wave(P-wave) and shear-wave(S-wave); P-Wave means medium particles oscillate along the propagating direction; S-wave represents particles oscillating perpendicular to the propagating direction.

This is great, thanks
Thanks for the Clear Video :)
nice video! and great explanation
Awesome!
Finally, got every single of my doubts cleared.
Wow! I was really astounded when he span the third sheet infront of the dimmed lamp, and it made it brighter! Almost seems to defy physics!
+Dan Coulson Welcome to quantum mechanics
yeah quantum mechanics defy physics lmao, but this absolutely didn't
This was a really nice video. East to understand:
This is an amazing video! Thank you so much!! :)
wow... really good.
Very helpful. Thank you.
I wish this video was twice as long and had gone into twice as much detail about circular polarization and how exactly one of the light components is slowed down by a quarter phase. But I appreciate the explanation.
Amazing sir
good way of explaining
Amazing !!! Thankss
oh great explanation. thanks
Thanks for the comments - I only have a left ear and thought the video was a bust. Now I know I just need to hear it in stereo or without cans at all.
Very good presentation... Keep going...
This is extremely interesting!!!
Nice Explanation.... wanted to know if Circularly and linearly polarized light both from the same source have equal intensity?
Really loved it thank you so much❤
you changed my life
awesome! thank you!
my right ear give you thumb down，cause you don't treat him equally。
Interesting! ❤

great video. you managed to make such a confusing topic so much easier.
If u teach Physics like this...I would have left my dream of becoming a doctor long ago
cool video
the best was the one black eye, when u close ur eye :D
you are goood, brabooooooo.
Thank you king
The sound is only to the gauche its very asmr thanks you very fascinating
dude ur awesome
Me likey the attitude......now thats ....COOL👍
My left ear learnt a lot about circular polarisation. My right one, not so much.
Quality explaination
awesome
The Mantis Shrimp eyes... :o

It is because the circular polarized light always has an amplitude isn't it? I mean the function has no roots. Am I correct with this?
Nice trick at 1:45. I assume that you put a circular polarizer in front of the camera to achieve that effect.
yeahhhahahahahaha that's amazing. it's always exciting for me to wonder and see how the effects observable to us can be transmitted to the camera (and by extension, to other corresponding devices too)

I'd not have thought of Dr. Cox explaining quantum physics to me in a magician (sleight of hand) style.
So circular polarizers have a bandwidth?
Dang, just when you thought things might be simple...
Thanks!
could you tell how polarized glass made?
Gold.
perfect
very helpful thanks
super easy explaination
Any advice before watching 👀,looks like I need one...
well explained Sir
'Heyy we're the Beatles.' Oh lordy

Why do we need Circular polarization of light for Photoelastic study of Stresses?
Stress causes circular polarization because it creates a different index of refraction (speed of light) along the axis of stress
Regarding the experiment with the mirror and 3-D glasses, that demonstration is misleading in my opinion and needs to be clarified.

Hi. Am I to understand that electromagnetic waves are not electromagnetic, but are electro-electric? Please clarify! Thanks.

The reason why we ignore the magnetic part is because we know it's perpendicular to the vector sum of the electric part. Or so I assume based on this video.
