SonoShine

Short answer: Sonoluminescence is the emission of brief flashes of light from bubbles in a liquid driven by intense sound. The sound's pressure swings make bubbles grow and then collapse violently, compressing the gas inside to temperatures of thousands of degrees.

The exact light-emitting mechanism is still debated. The footage shows a glowing bubble in a lab flask.

Video transcript: SonoShine: Sound Can Make Tiny Bubbles Flash With Light

Did you know? Sonoluminescence is a fascinating phenomenon where tiny bubbles in a liquid emit brief bursts of light when subjected to intense sound waves. This occurs when sound waves create alternating high-pressure and low-pressure regions in the liquid, causing bubbles to form, grow, and then collapse violently. During the collapse, the energy is concentrated in the bubble, producing temperatures of thousands of degrees and causing the bubble to emit light. This phenomenon is studied in physics and fluid dynamics. NOW YOU KNOW!
