Suppose a stick is struck against a frying pan in vacuum. Will the frying pan vibrate? Will we be able to hear the sound? Explain.

Question

Philoid · Accepted Answer

Yes, the frying pan will vibrate. No we will not be able to hear the sound because:

⇒ The vibrations need a medium to travel.

⇒ In vacuum, sound cannot travel and there is no medium by which vibrations (sound) can produced.

⇒ Thus, we will not be able to hear the sound.
