Practice Questions
Question 1
A stationary sound source emits a frequency of 500 Hz. An observer is moving toward the source at 30 m/s. If the speed of sound is 340 m/s, what is the observed frequency?
Question 2
A sound source is moving toward a stationary observer at 20 m/s. The source emits a frequency of 800 Hz. If the speed of sound is 340 m/s, what is the observed frequency?
Question 3
A sound source is moving away from a stationary observer at 25 m/s. The source emits a frequency of 900 Hz. If the speed of sound is 340 m/s, what is the observed frequency?
Question 4
An observer is moving toward a stationary sound source at 15 m/s. The source emits a frequency of 1000 Hz. If the speed of sound is 340 m/s, what is the observed frequency?
Question 5
A sound source emits a frequency of 600 Hz. An observer is moving away from the source at 10 m/s. If the speed of sound is 340 m/s, what is the observed frequency?
