3. An ambulance travels down a highway at a speed of 120 km/h. Its siren emits sound at a frequency of 800 Hz. What is the frequency heard by a passenger in a car traveling at 90 km/h, in the opposite direction (a) as the car approaches the ambulance and (b) as the car moves away from the ambulance? Take the speed of sound as 340 m/s.

A state trooper chases a speeder along a straight stretch of road; both vehicles move at 159 km/h. The siren on the trooper's vehicle produces sound at a frequency of 600 Hz and the speed of sound in the air is 343 m/s. What is the Doppler shift in the frequency heard by the speeder?

A student uses an audio oscillator of adjustable frequency to measure the depth of a dried up well. Two successive resonances are heard at 17.5 Hz and 24.5 Hz. The speed of sound in air is 343 m/s. How deep is the well?

You do hot have a thermometer to measure temp you are able to measures the speed of sound through the air. If you measure the sound to be 349m/s. what is the air temp?
