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

He's well grounded in theory
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.

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.

Gross
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. Great video Mr Boom

Point proven
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 : )

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.

0:36 THAT SCARED THE SHIT OUTTA MEEE 💀💀
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.

At 03:15 I had to comment how the “waves” looked like a connect-the-dots
to make a Clam Shell!
Idk why but when he first shoes the ways moving u saw the bouncing back an forth but then it changed to the red moving to the right and the blue moving to the left and now they look like that and not them bouncing back and forth I’m so confused ahh
Rylee Baxley if you give me a time stamp I can rewatch the part. Mehdi gives a lot hypothetical or “invisible” information. He tried to get you to understand the whole pie including the heat waves from the oven elements as hey cross over to cook your pie.
If you don’t understand that is great, keep watching and one day it may make more and more sense.
Rylee Baxley at 01:45 there is a chart in the right hand corner with two waves at the top and one wave at the bottom.
The red/blue waves at top are what is really happening and the wave at the bottom is what you really see. The bottom wave is an average of the top two waves above it.
Awesome man. Your videos are highly addictive.
To be more precise: the vibrational behavior of a structure mainly depends on its density, Youngs modulus and poisson ratio which can be summarized as mass and stiffness properties.

Here's my caaaatt
you know, ive watched every video on this channel at least like 3 times but I can't leave
The crossover with my interest in detuned oscillators in music production is fascinating. Its the start of a classic wobble bass sound.
Hi Mehdi,
I think your 2 speaker setup failed because by gluing down the board at the edges (to the speakers) you fixed the medium's boundary conditions so that reflections are inevitable. If you wanted to try again, maybe glue them the same distance apart again, but use a full size foam board. You'd still get some reflections probably, but then you could try to impedance-match the foam board to the surrounding air by gluing on some wide paper fins along the rim. The waves should couple into the paper, then dissipate the energy into the air, making your whole setup a better approximation of an infinite medium. Then you shouldn't have to worry about reflections
The solution to your problem is not frequency difference. Instead, use identical speakers at both ends with the same frequency, but with a 90 degree phase shift (we use NI DAC to do that). This will create a traveling wave in the structure and will move salt particles for you. Let me know how it works. Excellent video by the way! you are awesome! Keep up the good work
how exactly do you achieve a 90 degree phase shift? Ive been looking into the idea of Phases but dont seem to really get how you would achieve that here
