These shapes you ... ( 3 weeks ago by elanus81)
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.
It can be explained ... ( 3 weeks ago by elanus81)
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

in a way. i can't remember exactly how to explain it, it's kind of like looking at an escher painting. a high pitch vs. a low pitch in this experiment is like the middle of an escher paining vs. the edges

Higher pitch = ... ( 1 week ago by Klimpenkens)
Higher pitch = Shorter Wavelength = More of the pattern is shown on the platter.
It's not that the lower pitches have a less complex pattern, it's that less of the pattern can fit onto the platter.

we did this in my physics class sophomore year, we hit a frequency and 3 kids threw up, it was hilarious, but still cool.

Hmm... the paterns become more detailed as the notes go higher, I wonder why? Can any shed some light on this? I'm a little to lazy to google right now... :P
The patterns do not ... ( 2 days ago by elanus81)
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.
