Or, better yet, do a web search. I got 400 hits!

OK, Greg, here's your chance for a Nobel Prize: explain
sonoluminescence. Nobody knows how it works. In water a
converging sound wave sets up a pressure field tat acts on a
tiny bubble in the water in such a way as to create a pulse of
light. When this was first discovered years ago people were
amazed. They were more amazed as the time duration of the light
pulse was measured. I think it was only abou 10 years ago that
experimental equipment got good enough (fast enough) to measure
these bursts which are on the order of 50 picoseconds ( 50 times
ten raised to the minus 12 seconds or 50 millionths of a
millionth of a second).

It is presently a subject of some intense research both
experimental and theoretical.
