One day when the speed of sound in air is 343 m/s, a fire truck traveling at v = 29 m/s has a siren which produces a frequency of f = 402 Hz. What frequency, in units of hertz, does the driver of the truck hear?
Added by Asunci-N F.
Step 1
We are given the speed of sound in air (v_sound = 343 m/s), the speed of the fire truck (v_truck = 29 m/s), and the frequency of the siren (f_siren = 402 Hz). We need to find the frequency heard by the driver of the truck (f_driver). The Doppler effect formula for Show more…

"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?"
