The Visual Patterns of Audio Frequencies Seen through Vibrating Sand

Youtube user Brusspup (previously here and here) who often explores the intersection between art and science just released this new video featuring the Chladni plate experiment. First a black metal plate is attached to a tone generator and then sand is poured on the plate. As the speaker is cycled through various frequencies the sand naturally gravitates to the area where the least amount of vibration occurs causing fascinating geometric patterns to emerge. There’s actually a mathematical law that determines how each shape will form, the higher the frequency the more complex the pattern.
