It is due to the Sonoluminescence effect.

Plz mark thanks....
Sonoluminescence is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound. the bubble contains mainly inert noble gas such as argon or xenon (air contains about 1% argon, and the amount dissolved in water is too great; for sonoluminescence to occur, the concentration must be reduced to 20–40% of its equilibrium value) and varying amounts of water vapor.
Chemical reactions cause nitrogen and oxygen to be removed from the bubble after about one hundred expansion-collapse cycles. The bubble will then begin to emit light.
