This phenomenon is called sonoluminescence. Sonoluminescence - a physical phenomenon of transformation of sound into light. Scientists have 70 years of trying to explain it, but no one has yet succeeded. Nobody was able to explain how sound can create an air bubble of light, but it happens.

However, in the explanation of the sonoluminescence have some progress. First, physicists believed that all matter is force, but in the 1980s they found that the sound wave expands and heats the gas bubbles inside them to a higher temperature than the surface of the sun. Physicists thought, bursting with the heat, the bubble creates a glowing plasma, but even 30 years later, it's still just a hypothesis.

Nevertheless, the researchers believe that this phenomenon should involve different physical mechanisms should be several types of sonoluminescence. Already it is known that sonoluminescence depending on the size of the bubble, moreover, when it bursts, OH emission occurs.

In the future, probably, the sound and the gas can be used for underwater lighting, beyond the limitations of conventional lamps.
