WebSingle-bubble sonoluminescence – a single, cavitating bubble. Sonoluminescence is the emission of light from imploding bubbles in a liquid when excited by sound. Sonoluminescence was first discovered in 1934 at the University of Cologne. It occurs when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to … Webelectromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength.
