FACT: IF YOU COLLAPSE AN UNDERWATER BUBBLE WITH SOUND WAVES, IT PRODUCES LIGHT, NOBODY EXACTLY KNOWS WHY!
We all know that energy can be transformed from one form to another. That's what we all learned at school. Those of you who are really reading this for curiosity, chances are, that you were also curious at school to know about the various conversions of energy from one form to another.
If that is the case, then this article is a bonanza of sorts for you!
You must have thought whether sound energy can be converted to light directly (If you did'nt think about it then, give it a thought now :P ).
Well, it seems sound energy CAN be directly converted to light energy.
Get a glass of water( make sure there are small air bubbles in it) , impose on it some sound waves, and voila! physics rewards you by light energy (only for a few picoseconds though ).
This phenomenon of generating light energy from sound energy is called "SONOLUMINESENCE".
Sonoluminescence: The phenomenon in which acoustic energy is concentrated into collapsing bubbles that emit picosecond pulses of broadband light.
Calculations indicate that peak temperatures inside the bubbles may exceed 12 million K, that peak pressures may reach 100 million atmospheres, could initiate D-D fusion.
Harnessing the high energy release would lead to the development of
revolutionary propulsion and power systems

THE SONOLUMINESCENCE PROCESS
A complete understanding as to "how" light is emitted from the air bubble on imposition of sound waves
is still not developed.
However, according to Seth J. Putterman, when the sound energy is focussed on the air bubble, the size of
the air-bubble first increases, followed by a sudden drop in size and emission of light and the collapse of the bubble.
It has been found out that during the light emission from the air bubble, the temperatures inside it is calculated
to be more than the temperature of sun. This extreme amount of temperature can be used to start a fusion reaction.
This points towards applications for safe and clean energy generation.
