Today, astronomers use these words to describe changes in the wavelengths of radio waves or X-rays as comfortably as they use them to describe changes in visible light.

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.
