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.

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 : )

7:47 when your plate oscillates whenever your wii crashes
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
Honestly, I'm suprised that speaker even survived for a small second. 60Hz sounds great

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.

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
0:36 is what we all want to see.
Omg!! You won't believe how many times I wound back to watch that speaker light up! Just brilliant!!

Take with a grain of salt I'm a computer science student, I am NOT an engineer or physicist, so naturally I'm not all too familiar with how these things work. But I can extrapolate some of the concepts to attempt a solution. What I'm seeing is a loop that is supposed to increase the position of the salt in the X or Y coordinate based on the difference of two variables. The reason why I think it is not working is because the maximum frequency acts as a limit for the loop, which is causing it to terminate early. If you were to steadily increase the difference (and by extension the maximum frequency) as it goes, the loop would eventually push the salt off of the plate (or make it vibrate into a funky looking pattern and not sweep it at all). You'll have to manually terminate the loop tho, as I don't thing the system has a way of knowing when the salt is off the plate, but at least it would sweep it off (in theory).
If anyone knows better, please do let me know, I AM curious about the rest of the sciences so it would be cool to know whether or not my theory would or wouldn't work
Today is a Good Day I just Got Two 220V Shocks ,Opens YT and ....TADA
New Video from ElectroBoom
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

You can visualize this in ANSYS. Just run a pre-stressed modal analysis and specify the number of harmonic indices and the number of frequencies to expand. Contour plots will show different mode shapes of the plate. We use this principle to analyze turbine airfoils.
