Light from distant stars and galaxies can be shifted in much the same way. Like sound, light is a wave that can be described in terms of its frequency, the number of wave peaks that pass by each second. WebThe Doppler effect causes a wave to be received with a frequency different from the one with which it is emitted as a result of the motion of the emitter and/or receiver. The effects are most commonly studied in sound waves and light waves. It is noticeable when a train or a car passes by while emitting a horn sound.
