Doppler shift is also known as the Doppler effect is characterized as a change in wavelength or wave frequency with respect to the observer who is in motion relative to the wave source. The phenomenon was described by the Austrian physicist Christian Doppler in the year 1842.
WebAn article by Markus Poessel. 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. Some of its manifestations, we know from everyday life, such as a fire engine’s siren abruptly changing pitch as the engine passes by; others are of ...
