Doppler effect - Supersonic source

This animation illustrates Doppler effect when the source of sound is moving faster than the speed of sound (here the source is moving at mach 2, which is twice the speed of sound). A shock wave is created (mach cone): this is the sonic boom. Cette animation illustre l'effet Doppler lorsque la source sonore se d?place ? une vitesse sup?rieure ? la vitesse du son (ici, la source se d?place ? mach 2: le double de la vitesse du son). Il en r?sulte la formation d'une onde de choc (c?ne de Mach). ? la fronti?re de ce c?ne, l'intensit? sonore est tr?s ?lev?e (bang supersonique).
