Doppler Effect for Wave SOURCE

[justadream]

Let's say a car is moving at 20 m/s. Its engine makes noise.

Typically, speed of sound is 340 m/s. But in the perspective of the car, is the sound shifted?


I could be wrong but I believe TBR Physics II page 26 #19 (see answer explanation) seems to say that the answer is "yes".

No, that's not correct. Can you share what TBR says?

Sike, my mistake. I misinterpreted the question.
