From UPSC perspective, the following things are important :
Prelims level: Sonoluminescence
Why in the News?
Recent studies have provided deeper insights into the mechanics of Sonoluminescence, particularly the conditions under which light is emitted from collapsing bubbles in liquids.
What is Sonoluminescence?
|
Mystery behind Sonoluminescence
- Although the general mechanism is understood, the exact details of how the light is produced remain a mystery.
- Scientists are still exploring the precise processes that cause the gases inside the bubble to ionize and emit light at such high temperatures.
Examples of Sonoluminescence
- Controlled Experiments: In laboratory settings, scientists create sonoluminescence by trapping a bubble in a liquid and subjecting it to high-frequency sound waves.
- Pistol Shrimp: When the shrimp (marine creature with a specialized claw) snaps its claw shut, it shoots out a jet of water that moves so fast it creates a low-pressure bubble. The bubble then collapses, producing a loud sound, intense heat, and sometimes a brief flash of light.
