Question

moving with the source

1. predict what you think you would hear if you were moving with the firetruck as it produces sound waves. would you hear a change in pitch because of the doppler effect?

type your answer here.

Explanation:

The Doppler effect causes pitch changes when there is a relative speed difference between the sound source and the observer. If you move with the firetruck, your speed relative to the truck (the sound source) is zero. There is no relative motion to compress or stretch the sound waves, so the observed frequency (pitch) stays constant.

Answer:

You would hear a constant, unchanging pitch, and you would NOT hear a pitch change due to the Doppler effect. This is because there is no relative motion between you (the observer) and the firetruck (the sound source).
