The Doppler Effect is _____________________.
A)the speed of light divided by the frequency of the wave
B)the change in the wavelength divided by the change in the frequency
C)the change in frequency and wavelength of a wave due to motion between the source and observer
D)the decrease in wave intensity with increasing distance from the source

Question

Quizplus · Accepted Answer

The Doppler Effect refers to the change in frequency and wavelength of a wave due to relative motion between the source of the wave and the observer. This can cause waves to appear compressed or stretched out, which can be observed in phenomena such as the changing pitch of a siren as a police car moves towards or away from an observer. Option A is the formula for calculating the speed of a wave, while option B describes the relationship between wavelength and frequency in a wave. Option D describes the phenomenon of wave attenuation, which is not related to the Doppler Effect.
