Question

A ringing alarm clock is placed into vacum... but still we can hear its ticking sound why?​

Answer 1

When a ringing alarm clock is placed in vacuum, we would not be able to hear it's ticking sound because sound cannot travel in vacuum. ... While, in solids, liquids, gases, there are particles through which sound waves travel easily. The particles vibrate due to the sound waves, helping us to hear sound.
