Question

Quizplus · Accepted Answer

This phenomenon is known as the Doppler Effect and results in a shift in the frequency of the sound waves perceived by an observer when there is relative motion between the source of the sound and the observer. If the source is moving away from the observer, the frequency perceived is lower than the actual frequency emitted by the source.
