- A train whistle (f = 400 Hz) sounds higher or lower in frequency depending on whether it approaches or recedes. (a) Prove that the difference in frequency between the approaching and receding train whistle is f=2u/v1u2/v2f where u is the speed of the train and v is the speed of sound. (b) Calculate this difference for a train moving at a speed of 130 km/h. Take the speed of sound in air to be 340 m/s.arrow_forwardAn ambulance moving at 42 m/s sounds its siren whose frequency is 450 Hz. A car is moving in the same direction as the ambulance at 25 m/s. What frequency does a person in the car hear (a) as the ambulance approaches the car? (b) Alter the ambulance passes the car?arrow_forwardAn interstate highway has been built through a neighborhood in a city. In the afternoon, the sound level in an apartment in the neighborhood is 80.0 dB as 100 cars pass outside the window every minute. Late at night, the traffic flow is only five cars per minute.

- A train is moving past a crossing where cars are waiting for it to pass. While waiting, the driver of the lead car becomes sleepy and rests his head on the steering wheel, unintentionally activating the cars horn. A passenger in the back of the train hears the horns sound at a frequency of 428 Hz and a passenger in the front hears it at 402 Hz. Find (a) the trains speed and (b) the horns frequency, assuming the sound travels along the tracks.arrow_forwardA tunnel under a river is 2.00 km long.
