Question

Three sources of sound are distributed along a line, as shown in the figure. v is the speed of sound. Source A is at rest, and it emits sound waves with a frequency of 600 Hz. Source B is traveling at v/5 to the right, and it emits sound waves with a frequency of 1110 Hz. Source C is traveling at a speed of v/3 to the left, and it emits sound waves with a frequency of 1600 Hz. A, B, and C also detect the sound waves emitted by the other sources. All the questions below pertain to when the three sources of sound are at the locations shown in the figure below.

All the questions below pertain to when the three sources of sound are at the locations shown in the figure below. What frequency does B observe for the waves emitted by C? (B = observer; C = source) I cant get the right answer

Explanation / Answer

The Doppler effect formula for when an observer moves toward a source, and the source moves toward the observer is

f' = f(v + vo)/(v - vs)

f' = f (v + v/5)/(v - v/3)

Simplify

f' = 9/5f

f' = (9/5)(1600)

f' = 2880 Hz
