What is the Doppler effect?
The observed change in frequency of sound or light because of the relative motion of a wave source and the observer.
The observed change in amplitude of sound or light because of the relative motion of a wave source and the observer.
The observed change in wave speed of sound or light because of the relative motion of a wave source and the observer.
The observed change in equilibrium position of sound or light because of the relative motion of a wave source and the observer.
When a plane moves faster than the speed of sound and breaks the sound barrier:
The Doppler effect is observed
A sonic boom is produced
The plane will slow down
A infrared light will be produced
