Doppler effect

Doppler effect

the apparent increase or decrease in wavelength or frequency observed when a source of electromagnetic radiation or sound approaches or recedes from the observer or listener, producing a change in hue or pitch. The total Doppler effect may result from motion of the source, observer, or medium (such as a sound wave). [Christian Andreas Doppler (1803–1853), Austrian mathematician]
