The Doppler effect (or the Doppler shift) is the change in frequency of a wave (or
other periodic event) for an observer moving relative to its source. It is named ...
The Doppler effect is observed whenever the source of waves is moving with
respect to an observer. The Doppler effect can be described as the effect
The frequency of a wave-like signal - such as sound or light - depends on the
movement of the sender and of the receiver. This is known as the Doppler effect.
