Question

Which one of the following statements regarding the Doppler Effectis FALSE?

(A) The observed frequency is greater than the sourcefrequency if the source is moving
towards a stationary observer.
(B) The change in frequency is dependent on the speed of the sourcerelative to the speed of
sound in the medium.
(C) The change in frequency depends on the distance between sourceand observer.
(D) If the source moves towards a stationary observer at the speedof sound, the observed
frequency becomes infinite.
(E) The observed frequency is greater than the source frequency ifthe source is stationary
and the observer is moving towards the source.

Explanation / Answer

C - If you look at the equations for the dopplereffect, none of them contain an intial distance, only change indistance over time.
