Eli5: How does sonoluminescence creates light?
In: Physics
The temperature in the bubble gets tens of thousands of Kelvin hot. We don’t know exactly what causes it, it could just be the heat producing light. I think this is most likely, but it could be from moving electric charges or other effects.
The sound of a sufficient intensity can cause a bubble to collapse and as a result of the collapse produce a short burst of light. https://youtu.be/cZjYoWFexrY
