Single Bubble Sonoluminescence (SBSL) or Synchronous Sonoluminescence is simply producing light from sound. In essence, SBSL is a process of using sine waves to vibrate an air bubble within a flask of water at resonant frequency. SBSL is achieved when a stable bubble is expanded within a pressure anti-node during a negative pressure cycle. During the positive pressure cycle, the water pressure within the flask collapses the bubble. This reaction, which I will try to demonstrate, will then produce light when the bubble radius reaches its minimum. Although many different theories have tried to explain SBSL, no single theory can yet account for all the observed phenomena which makes SBSL a very exciting new field for the future.
