effet Doppler
Sign in to saveAlso known as Doppler's principle, Doppler shift
phénomène physique de décalage de la fréquence d’une onde
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.

L'effet Doppler, ou effet Doppler-Fizeau, est le décalage de fréquence d’une onde (mécanique, acoustique, électromagnétique ou d'une autre nature) observé entre les mesures à l'émission et à la réception, lorsque la distance entre l'émetteur et le récepteur varie au cours du temps. Si on désigne de façon générale ce phénomène physique sous le nom d'effet Doppler, le nom d'« effet Doppler-Fizeau » est réservé aux ondes électromagnétiques.
