Mehdi! Thank you for the shoutout! This was epic, and hilarious as usual. I can’t believe you even attempted to move the particles, that’s EXTRA. Btw, you stumbled on some really interesting physics at 5:25 that I may or may not have already been thinking about for a future video….
:D thanks! I was also wondering why light particles seem to like to stay on the anti-nodes. I'll wait to watch your explanation!
@@ElectroBOOM in your 2 speaker setup, you had the speakers glued to the opposite ends of the foamboard. try glueing them on the same side of the foamboard adjacent to each other
@@ElectroBOOM in fact, now that I think about it, you use 2 speakers at opposite ends to create the beats (pulses) by summing up the 100hz and 101hz waves mechanically at the foam board. Why not try summing the 100 and 101hz signals electrically and then feed the resultant beats (pulses) to the speaker driver?
@@ElectroBOOM you see, the scope (at 8:00) shows the beats (which is the result of the 2 frequencies being electrically summed) produces a wave whose nodes move in one direction.
@@ElectroBOOM try the experiment with the speaker mounted at one end instead of the centre

I'm from China. I got here using VPN. Many people do the same for "political sensitive" videos banned in China. But I'm here for watching a guy testing his resistance with live wires and showing graphs, formulas I once struggled with during my college days. I now work in IT industry so I don't touch sine waves and care about grounding anymore. But your videos always bring back my good old memories in the college labs where I sweated hard each time before I try to connect some wires to another or turn up a switch.
Since the China-US trade war began I found it's becoming harder to get out. Many VPN and foreign IPs are being blocked more frequently than before. I have to switch VPN service every another week or so. But I think all these worth it.
Look bro China has been bullying our country (Philippines) lately, but I can tell that you are a brother as well so I hope you well.

Hi ElectroBOOM, the other day in engineering (before school ended haha), my teacher started talking about Kirchhoff vs. Faraday’s voltage systems and asked if anyone knew about it, and I had seen your video about it, so I raised my hand and said what I knew from your video, and my teacher was really impressed! So thanks! :)

Your videos are so much fun and so educational! As an older engineer still building lots of stuff, I still love watching your videos. You would be a wonderful professor at a university! And I never get tired of waiting anxiously for the high voltage discharge or burn shriek!
Mehdi, I've found your channel as well as its content to be glorious, it takes nothing less than a genius to create content which is not only informative and entertaining, but also something as a viewer you want to see and inherently learn from it, personally I am a big fan of learning the ways something works through experiencing how it fails also, it gives me insight to recognize when something is not operating the way it should, because I've experienced the ways it doesn't or shouldn't work. I'm learning without even trying! If you ever read this comment, I want you to know that I am someone who's been struggling to learn about electricity for years and now, through your content, I am finally starting to understand it. I can finally call a truce with electricity and create a path to understand it. I appreciate your hard work.

Thats awesome, the spots of salt inbetween standing
waves that you showed reminds me of patterns i see with magnets with ferrofluid and ferrocell and also water vortices
A sound is absorbed when moving to a more dense mass and reflects when the mass is less. If you have a circular poster board with a more dense material like nylon plastic on it's out perimeter the sound generated will be absorbed into the the poster board then will enter the plastic then will reflect within the plastic reflecting back and forth within the plastic without reentering the poster board.

As always your video are interesting... Thank you sir....🙏👍😊
Beautiful experiment MR. Thanx!!!
At the end of the video you showed an example of movement through the air. I could imagine this having some very useful applications in industrial automation. Moving particles without the need for conveyors/buckets/etc. You could also probably sort particles by tuning to certain resonant frequencies, and only the important ones float up.

Your old persian subscriber here.
Since you had 100k subscriber.
By using a lot of ultrasonic transducers, like you mentioned at the end, you can also create certain points where the 40kHz gets modulated to around 200Hz by overlapping. You can actually feel those spots. So you can create haptic feedback by simulating shapes with those spots.
Awesome man. Your videos are highly addictive.
I’ve been watching this channel long enough to know the second you brought out that pane of glass it would be broken by the end of the video
I just narrowed my eyes and waited for it to crack... Sure didn't take long.
I know, right . LOL
Honestly, I'm suprised that speaker even survived for a small second. 60Hz sounds great
very cool, all your videos are interesting! you've inspired me to learn electronics. so far i've built a power supply, a function generator, and a mini theremin.
This is amazingly cool looking!

I knew it was theoretically possible but ive never seen it done practically .
Thank you .You mad nerd !
This guy explains ideas in the simplest way possible , keep it up mehdi, you're the best 💪
Hello Mehdi. I have 2 suggestions for this:
(1) Maybe it is possible to set the input wave generator with a variable phase shift. In this way, you will be able to change the phase shift and, in turn, move the position of the zero point of the wave. You can then change the phase shift manually (with a knob) or else use a ramp generator to control the phase shift linearly.
(2) In your experiment, the salt was stuck moving left-right around a point maybe because the COMBINED WAVE was too fast and the salt could not follow. Imagine the combined wave being a sea wave and the salt being a person on a surf board. If the wave is slow enough for the guy to follow, then the guy would be able to ride the wave without problems and continue to move in one direction ... But if the wave is too fast, the surfboard would be slow and it would eventually end up on the peak of the wave and then on the other side of the wave, therefore moving backwards (down the trailing side of the wave) ... Following this reasoning, maybe your combined wave was trying to push the salt to the left, but then the wave was too fast and its peak went past the salt which means that now the salt was on the falling side of the wave which made the salt move to right until the next wave came to repeat the process. It would have been good to try to slow the COMBINED wave using F1=100Hz and F2=100.1Hz (rather than 101Hz) to make the combined wave travel much slower.
Actually, it would be interesting if you make such a test for point 2 as a follow-up video : )

The particle cloud coalescence and disintegration is amazing. Looks like there are some superior harmonics that are able to separate smaller particles and, at different amplitude, overcome electrostatic attraction between them.

We use to study the difference between 2 frequencies in music classes and would often refer to it as the Beating effect. From what I remember a larger surface with a longer standing wave resonance would give you a better chance of seeing the visual effect. If you ever revisit this idea I would recommend a large surface and one speaker with a 2 channel audio mixer with 2 frequencies close to each other to create the moving standing wave. Did you know that we can only hear the beating effect with a difference of up to 20hz and that varies human to human with their hearing range. The beating effect is also used to create a non lethal weapon with sound and radio waves!!! Some of the weapons built feels like your skin is melting.
