Sonoluminescence was first observed in 1934 by H. Frenzel and H. Schulte indirectly by looking at acoustic radar in an ultrasonic water bath [1]. Sonoluminescence is the production of light from sound. Sonoluminescence or SL is the phenomena in which a bubble on the scale of microns is spatially trapped and oscillated by an acoustic field where each compression on the bubble causes a small burst of light [2]. Light emission comes in the form of extrmely short bursts when sonoluminescing. In the case of this experiment a bubble was trapped in a cylinder fileld with liquid where then the acoustic field can be applied. If a laser is but on the trapped bubble then with a photomultiplier the scattering from the bubble can be measured, known as mie scattering. The purpose of this lab is to observe the sonoluminescing phenomena, measure mie scattering,to determine the radius of the bubble in time, and obtain the optical spectrum of SL using diffrent fliters in front of the photomuliplier.
