Sonoluminescence is a phenomenon that occurs when a small gas bubble is acoustically suspended and periodically driven in a liquid solution at ultrasonic frequencies, resulting in bubble collapse, cavitation, and light emission. The thermal energy that is released from the bubble collapse is so great that it can cause weak light emission. [1]
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 collapse quickly, emitting a burst of light.
An interior light is a type of light that is generally used to illuminate the cabin of a vehicle. Interior lighting setups can vary greatly in both complexity and size, and certain vehicles, depending on a number of factors, may use simpler, more utilitarian lighting configurations, or choose to incorporate grander systems (known as ambient lighting).
