Meaning and Definition
The emission of brief flashes of light from bubbles in a liquid when excited by sound waves.
A physical phenomenon where acoustic cavitation (the formation, growth, and implosive collapse of bubbles in a liquid) produces light. This process converts sound energy into light energy and is studied in fields like fluid dynamics, acoustics, and photonics.

FAQ
Frequently Asked Questions
It is caused by the rapid implosive collapse of microscopic bubbles in a liquid, driven by intense sound waves. The collapse creates extremely high temperatures and pressures inside the bubble, leading to light emission.
In a darkened room, the faint, brief flashes of light from multi-bubble sonoluminescence can sometimes be seen as a diffuse glow. Single-bubble sonoluminescence produces a steady, pinpoint flash visible in the dark.
Some highly speculative theories (like 'bubble fusion') have suggested the extreme conditions inside a collapsing bubble might allow for nuclear fusion, but this remains unproven and controversial. Standard sonoluminescence is a non-nuclear process.
Currently, it is primarily a laboratory phenomenon studied for fundamental science. Potential applications are exploratory and include chemical catalysis, medical therapies using cavitation, and advanced sonar technology.
