| 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 = ... ( 3 weeks 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. |

| Hmm... the paterns ... ( 2 weeks ago by mechanism8) |
| 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 weeks 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. |

| What you're seeing ... ( 5 days ago by geshel) |
| What you're seeing are some of the vibrational modes of a square plate - not exactly sound waves. The sound causes the plate to vibrate, and some frequencies correspond to resonances of the plate. At those frequencies, all the vibrations in the plate "line up" in the patterns you're seeing. At the frequencies in between, not much is happening. That's why the sand seems to "jump" to a new pattern - that's when the next resonant frequency is hit. |
| The plate vibrates ... ( 5 days ago by geshel) |
| The plate vibrates up and down. The places where there's no sand is where it is vibrating up and down the most; the sand all goes to where it's vibrating the least. |

| This vid' has been copied way to much... It's cool even though the plate is a bit lopsided. Should be done with better equipment. |
