Sound cannot travel in vacuum. Describe an experiment to demonstrate this.
Experiment to demonstrate that sound cannot travel in vacuum:
Experiment 1:
We place a bell in an airtight jar and after ringing the bell, the sound is heard clearly. So it is proved that sound can travel in the air.
Experiment 2:
We place a bell in an air-tight jar that is connected to a vacuum pump. After ringing the bell we hear no sound. That proves that sound cannot travel in vacuum.
