A speaker on a car produces a 150 Hz sound wave when parked. The car starts to drive toward a pedestrian standing by the road, and the pedestrian hears the sound shift to 160 Hz when the car starts to drive toward them. The car passes the pedestrian and drives away from them. What frequency would the pedestrian hear as the car drives away? Assume the speaker continuously produces the same frequency, the car maintains the same speed, and the...

The security alarm on a parked car goes off and produces a frequency of 1010 Hz. The speed of sound is 343 m/s. As you drive toward this parked car, pass it, and drive away, you observe the frequency to change by 76.0 Hz. At what speed are you driving?

The security alarm on a parked car goes off and produces a frequency of 830 Hz. The speed of sound is 343 m/s. As you drive toward this parked car, pass it, and drive away, you observe the frequency to change by 56.1 Hz. At what speed are you driving?

A police car drives past you with its siren on. While the car is approaching, you hear a frequency of 550 Hz. A Recalling that the speed of sound is 767 mph, what is the speed of the police car if the siren has a frequency of 507 Hz when neither you nor the car are moving? B What would the apparent frequency of the siren be if you were driving toward the parked police car at this same speed....

A car sounding its horn (rated by the manufacturer at 600 Hz) is moving at 15.0 m/s toward the east. A stationary observer is standing due east of the oncoming car. 1) What frequency will he hear assuming that the speed of sound is 343 m/s? (Express your answer to two significant figures.) 2) What if the observer is standing due west of the car as it drives away? (Express your answer to two significant figures.)

When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...
