A source of sound waves of frequency 0.7 kHz is traveling during the air at 0.45times the speed of sound.

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

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