Definition of the Doppler Shift:
The Doppler shift is the alteration of the frequency observed of waves that occurs whenever the wave source is moving towards or away from the observer (or the observer is moving towards or away from the wave source).


 
The Doppler shift can be observed of any type of wave (sound wave, light waves, etc.) as long as there is motion of the wave source relative to the observer. The wave source can be moving towards or away from the observer. The observer can be moving towards or away from the wave source. Or both wave source and observer can be moving towards or away from each other. As long as the distance between wave source and observer is increasing or decreasing, the Doppler shift is observed.
