sonoluminescence – if an underwater bubble collapsed with a sound wave, light is produced.
If you collapse an underwater bubble with a sound
wave, light is produced, and nobody knows why.
It’s a phenomenon called sonoluminescence.
this effect was first discovered at the University of
Cologne in 1934 as a result of work on sonar.
it is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound.
Sonoluminescence is a physical occurence by which
sound turns into light. Scientists have been trying for
70 years to explain it, but have had no success. No one has managed to explain how a bubble of air in water collapse with sound wave to cause light, but it happens.
