(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)
