AI overview

The Doppler effect is the change in frequency of a wave that an observer perceives when either the observer or the source of the wave is moving. This matters because it explains everyday experiences like why a siren sounds higher-pitched as an ambulance approaches and lower-pitched as it moves away, and it's also used in practical applications like radar speed guns and astronomy.
