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.

On what does the speed of mechanical waves depend?

A: Speed of light in a medium is independent of the motion of the source relative to the medium. R: Speed of light in a medium depends on the motion of the observer relative to the medium.

(A) : Relative to an observer at rest in a medium the speed of a mechanical wave in that medium (1) depends only on elastic and other properties (such as mass density) of the medium. It does not depend on the velocity of the source. (B): For an observer moving with velocity v_(0) relative to the medium, the speed of a wave is obviously different from v and is given by v+-v_(0)
