Question
A particle of the medium near to the vibrating object _____.
- Vibrates alone
- Vibrates and sets the next particle to vibration
- It comes to rest
- First b then c
Hint:
When an object vibrates, it causes movement in neighboring particles.
The correct answer is: First b then c
- A particle of the medium in contact with the vibrating object is first displaced from its equilibrium position.
- It then exerts a force on the adjacent particle.
- And comes to rest.
- As a result of which the adjacent particle gets displaced from its position of rest and vibrates.
