Textbook Question
Chapter 16, Problem 16.22DQ
In case 1, a source of sound approaches a stationary observer at speed u. In case 2, the observer moves toward the stationary source at the same speed u. If the source is always producing the same frequency sound, will the observer hear the same frequency in both cases, since the relative speed is the same each time? Why or why not?

A fire truck emits a sound with frequency of 775Hz
a. What is the frequency detected by stationary observer if the fire truck is moving 45m/s towards observer?
b. What frequency will be frequency detected if the ambulance is moving 45m/s away from the observer? (the speed of sound in air at 20°C is 343 m/s)
A sound source emits an audible frequency of 512 Hz. Which would cause a greater Doppler shift in measured frequency at the observer?
Group of answer choices
a. The observer traveling toward a stationary source at 40 m/s.
b. The source traveling toward the stationary observer at 40 m/s.
c. The source and observer each traveling at 20 m/s toward each other.
d. All of these will be the same shift in frequency.
A listener at rest (with respect to the air and the ground) hears a signal of frequency f1 from a source moving toward him with a velocity of 15 m/s, due east. If the listener then moves toward the approaching source with a velocity of 25 m/s, due west, he hears a frequency f2 that differs from f1 by 37 Hz.What is the frequency of the source? (Take the speed of sound in air to be 340 m/s.)
