Summary

    Sonoluminescence (SL) involves trapping a gas bubble at a sonic antinode location in a resonance mode of a cell. The gas bubble is then subject to varying acoustic pressure that causes the bubble to collapse when the amplitude of the pressure is high enough. The gases within the bubble heat up and emit a very brief but ample amount of light. It is a phenomenon not fully understood and could prove to be quite important for energy production in the form of light if it one day could be.
