Questions and Answers

What is the frequency of the sound being emitted by the stationary source?

510 Hz

500 Hz (correct)

490 Hz

480 Hz

What is the typical velocity of sound in air at room temperature?

350 m/s

330 m/s

360 m/s

340 m/s (correct)

What is the equation used to calculate the frequency observed?

frequency observed = frequency of source * velocity of observer / velocity of sound (correct)

frequency observed = velocity of sound / frequency of source * velocity of observer

frequency observed = velocity of observer / velocity of sound * frequency of source

frequency observed = frequency of source * velocity of sound / velocity of observer
