What is the Doppler effect?
The observed change in frequency of sound or light because of the relative motion of a wave source and the observer.
The observed change in amplitude of sound or light because of the relative motion of a wave source and the observer.
The observed change in wave speed of sound or light because of the relative motion of a wave source and the observer.
The observed change in equilibrium position of sound or light because of the relative motion of a wave source and the observer.
