What is the Doppler effect?
The Doppler effect is the change in frequency that occurs when a source is moving relative to an observer. If the source moves away from the observer, the wavelength will be increased and therefore the frequency decreases. Similarly, if the source moves towards the observer, the wavelength will decrease and frequency is increased.
