Q. A wave source of frequency $v$ and an observer are located a fixed distance apart. Both the source and observer are stationary. However, the propagation medium (through which the waves travel at speed $v$ ) is moving at a uniform velocity $v_{m}$ in an arbitrary direction. If $v'$ is the frequency received by the observer then :

Waves

Solution:

As both source and observer are at rest the number of wavefronts / oscillations reaching to observer per unit time so frequency received will be same.
