Water Sonoluminescence

sonoluminescene sound into light image

A standing sound wave with a frequency of 40,000 cycles per second generates 40,000 flashes of light per second that can be seen with the unaided eye. The blue/purple dots are the micron-sized spots formed in water by imploding bubbles.  Photograph by Ed Kashi.  Felipe Gaitan was a big help to us.
