Compare the frequency of the wave source with the frequency measured by the observer. It may be useful if you compare the number of wave-crests emitted by the source with the number of wave-crests going through the point of observation. The number of wave-crests setting out from the wave source in 1 second gives the frequency of the wave source. |
