Sound Wave Frequencies Comparison Between Amy and Zach

What is the relationship between the frequencies of the sound waves heard by Amy and Zach as the source moves to the right?

A. F amy > F zach

B. F amy = F zach

C. F amy < F zach

Answer:

C. F amy < F zach

When both Amy and Zach are listening to the source of the sound waves that is moving to the right, the frequency of the sound heard by Amy is less than the frequency of the sound heard by Zach. This is due to the Doppler Effect, which causes a change in frequency of a wave in relation to an observer moving relative to the source of the wave.

The sound wave requires a medium to propagate, and as the source of the sound waves moves to the right, the frequency of sound detected by Amy, who is closer to the source, is lower than the frequency detected by Zach, who is further away from the source.

Therefore, based on the principle of the Doppler Effect, the frequency of the sound heard by Amy is less than Zach in this scenario.
