Assertion : Speed of mechanical wave in ...

Assertion : Speed of mechanical wave in the medium depends on the velocity of source, relative to an observer at rest.
Reason : Speed of mechanical wave is independent of the elastic and other properties such as mass density of the medium.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Relative to an observer at rest in a medium the speed of a mechanical wave in that medium d~pends only on elastic and other properties of the medium. It does not depend on the velocity of the source.
