Question

A wave source of frequency ν 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 ν ′ is the frequency received by the observer then:

Source and observer are fixed, so every wave front travels the same path through the uniformly moving medium and takes the same transit time. Wave fronts therefore arrive at the same rate they are emitted: ν ′ = ν .
