"A fire truck emitting a siren at 1000Hz moves at 45ms towards a jogger. The jogger is moving at 5ms towards the fire truck. Take the speed of sound to be 345ms. At what frequency does the jogger perceive the siren?"
Added by Dev D.
Step 1
This is done using the Doppler effect formula for sound: f' = f * (v + vo) / v where: f' is the perceived frequency, f is the emitted frequency, v is the speed of sound, and vo is the speed of the observer (jogger). Substituting the given values: f' = 1000Hz * Show more…

A fire truck is traveling at 35 m/s, with its siren going off at 842 Hz while you're at a traffic light. Assume the speed of sound of the siren is 341 m/s. What frequency do you hear the siren as it gets closer to you? What frequency do you hear as it passes you?

A fire truck is moving at a speed of 50 mph on a straight section of a highway with siren on. The sound is reflected back from a car in front and the truck driver detects a beat frequency of 6 Hz. What is the speed of the car and what is the frequency the car driver hears? The siren has a frequency of 600 Hz and the speed of sound in air is 344 m/s. Note there are two possibilities.
