Question

Quizplus · Accepted Answer

The Doppler effect is a change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It only involves changes in frequency, not speed (which remains constant for a given wave medium). Therefore, it is important to distinguish between frequency (the number of wave cycles per unit time) and speed (the distance traveled per unit time).
