Light from gas bubbles: Sonoluminescence measured

Researchers measured the chemical reactions and light emission from a single water bubble excited by sound waves, finding temperatures high enough to break water molecules apart. The experiment showed that only a small fraction of sound energy is converted into light, with most energy going into mechanical energy.

Research Uncovers Possible New Explanation For Sonoluminescence

Researchers have discovered a possible atomic process behind sonoluminescence, which could aid in the emerging field of sonochemistry. The study proposes that stimulated atoms decaying in unison emit light, explaining the short pulses observed in sonoluminescence.
