The ratio of the speed of the source to the speed of sound is 2.
If you are at rest at point A, and the source is emitting waves
that have a frequency of 660 Hz, what frequency do you
observe?
Homework Answers
n=660Hz
Observed Frequency or Apparent Frequency, na= (v/v+vs)n
= (v/v+2v)n
= (v/3v)660Hz
= 220Hz

A sound source producing 1.00-{rm kHz} waves moves toward a stationary listener atone-half the speed of sound
A sound source producing 1.00-{rm kHz} waves moves toward a stationary listener atone-half the speed of sound.The frequency that the listener will hear is2000 Hz.when the source is stationary and the listener moves towardthe source at one-half the speed of sound, the frequency that thelistener hear became 1500 Hz.Explain on physical grounds why thetwo frequencies differ.
