Sonoluminescence: an Introduction L sonoluminescence experiment What is sonoluminescence? Sonoluminescence is the emission of light by bubbles in a liquid excited by sound. It was first discovered by scientists at the University of Cologne in 1934, but was not considered very interesting at...To investigate the physical processes underlying the phenomenon of sonoluminescence, researchers attempted to measure the diameter and duration of single sonoluminescence flashes.

Direct Observations of Single Sonoluminescence Pulses The physical processes underlying the phenomenon of sonoluminescence have not been clearly resolved by previous measurements. The possibility that sonoluminescence might involve such extreme conditions that it could produce neutrons makes measurements of parameters such as the source temperature, diameter,...Maker of sonoluminescence kits.
