How does the sound produced by a vibrating object in a medium reach your ear ?

Text Solution

Verified by Experts

When a disturbance is created on an object, it starts vibrating and sets the particles of the medium in vibration. A particle of the medium is displaced from its mean position and it exerts a force on the adjacent particle. As a result, the adjacent particle is disturbed from its mean position. This process continues till the disturbance reaches our ear.
