![]() ![]() The value of the shift is dependent on details of the material the waves are traveling in. Because of this, the wavelength shifts and the frequency at which peaks arrive at the observer changes. ![]() As the source moves, each peak in the waveform it produces is emitted from a position which is closer or farther away (depending on whether the source is moving towards or away from the observer). ![]() The Doppler Effect describes the change in the wavelength and frequency of waves emitted by a source which is in motion relative to the observer.
