Sonoluminescence is the process of converting sound into light. There are two types of sonoluminescence, Multiple Bubble Sonoluminesence (MBSL) and Single Bubble Sonoluminescence (SBSL). In order to perform sonoluminescence, a flask full of water or whatever medium is connected to two piezoelectric transducers (used to amplify sound). The amplifiers feed into the transducers which then start emitting a very concentrated amount of sound, usually around 20-35 Khz. At this point in time, bubbles begin to form, dubbed as "cavitation bubbles." Once a cavitation bubble is captured in the middle of the flask, it is under the effects of the amplified sound. At a certain resonance point, the bubble begins to emit flashes of white light.
