A source of sound waves of frequency 1.2 kHz is traveling through the air at 0.25times the speed of sound.

a) What is the frequency of the sound received with a stationary observer if the source moves toward her?

kHz

b) Now, the source moves away from the stationary observer. What is the frequency of the sound received in this case?

kHz
