This is actually incredibly REALISTIC! I did this in my class this year for physics. The higher the frequency the more nodes that are created when a crest meets a trough. A crest is a high point in a wave and a trough is a low point in a wave. When they cross over it creates nodes, which in this case are the empty spaces where sand is not there.

It can be explained because as the pitch increases the sound wavelength decreases, producing shorter waves on the plate and thus reducing the distance between points where the waves cancel each other. The shapes appears to have higher complexity but is in fact smaller in scale
@ACDCBoy62

The loudspeaker under the plate is making the plate vibrate at whatever frequency the signal generator is set to. When the wavelength of the sound (which is inversely proportional to its frequency) is a multiple of the length of the metal sheet, the sheet vibrates in standing waves. You're seeing the sand settle in the nodes of the standing waves, where the metal isn't flexing back and forth.

Yes it is. The metal square plate has specific resonance frequencies and modes. The salt grains then gather at the "nodes" where the vibration is lowest

In general I think this field of study (exploring visual representations of sound waves) is called "Cymatics". Work by Swiss scientist, Hans Jenny has explored visual representation of sound waves on mediums. He found that when impacted by sound waves at a low frequency, sand will form itself into standing wave patterns such as concentric circles. The higher the frequency, the more complex the shapes became.

They're the normal modes of vibration for a square plate excited from the center. You can't really see sound waves, but here, the white grains go to the troughs of the vibration mode. The higher the frequency, the higher the vibration mode. All fundamental frequencies keep adding up, you can figure it out with Fourier Analysis...

Sonic transducer in the center of the plate, as the frequency increases, you see different vibrational modes of the plate. The areas where the salt settles are the null areas, where vibration is at a minimum. The shapes depend on freqency of the sound and the geometery of the plate, whether it's free or held at the boundaries, how it's suspended, thickness, type of material, etc.

These shapes you see are product of resonance waves going across the the plate, those waves cancel and amplify on certain spots on the surface, the salt they put on vibrates with those waves and stops where there is no vibration (where the waves cancel each other), the regularity is achieved by the regularity of the shape of the object an its material.

The patterns do not get strictly more detailed, they just get smaller due to the shorter wavelength (as noted before the spots with salt are the places where these waves cancel each other) if the waves are shorter the distance between these spots is shorter too, so the pattern is smaller, and more of it can be seen on the same plate. I you look into the central shape they reappear like the same note on different octaves.

You can 'see' the wavelength of the pitch by measuring from the center out in a straight line. The reason why it changes so suddenly even though the pitch is rising steadily, is because the metal only resonates at certain frequencies according to its size.
@Dobson90
16 жыл бұрын
Because there is no movement at the nodes the sand stays still and where there are anti nodes the sand is bounced either off the metal sheet or into a node. The different frequencies will cause the different patters because with the different frequencies you get both constructive and destructive interferences and so get different patterns

It is to do with the sheet of metals resonant frequency. There is a motor that is oscillating up and down in the middle. When the motor is oscillating at the same frequency as the metals resonant frequency standing waves occur. The standing waves are compromised of nodes and anti nodes (no amplitude and high or low amplitude)so because the metal is a uniform shape and the motor is in the middle you get uniform wave patterns emanating out from the center

Of course the table is vibrating... that's the point. The wave fronts are moving the table at specific points of overlap, pushing the sand around.
@DRIVEN1GTO

Its really pretty simple. All the shapes are a function of the resonance and breakup modes of the large square plate. There is a sound transducer at the center that is vibrating the plate. The sound ripples thru the plate and causes the white substance to collect in the 'valleys' created by the sound. No crazy magic - just physics.

@idusclothing There are certain frequencies whose wavelengths match resonate frequencies in the plate (frequencies whose wavelengths correspond the length of the plate) causing tumultuous motion that throws the salt to and fro till it settles in a node in the standing waveform.

The steep transition in pattern comes from the fact that not every frequency can produce the patterns, you can listen and see that these patterns only form when there is very loud noise, which means that the plate is at a resonant frequency, which produces this patterns. The user is just upping the frequency till he hits those normal modes which correspond to those resonant frequencies.
@TAshifter88

Great video! It's done by the grains falling to the areas that exhibit little-no wavelengths (nodes). The frequency emitted from the speaker below the tray increases, so different parts of the tray observe constructive interference (multiple wavelengths adding/subtracting from eachother) and "vibrate" more than the other parts. These parts that vibrate more tend to bounce the grains off of them, and the grains roll to the nodes (the parts where wavelengths cancel each other out).

I think I know what this is...the platform is just resonating at a certain pitch - the sound is creating sections on the platform where waves cancel out, and are therefore not vibrating (nodes), and other places where the waves amplify one another and vibrate tremendously (antinodes). The sand is literally being shook off of the antinodes, and is accumulated in the nodes because the nodes are not vibrating. The patterns show how the waves interact with one another and form these areas.
