(a) What frequency is received by a person watching an oncoming ambulance moving at 105 km/h and emitting a steady 833 Hz sound from its siren? The speed of sound on this day is 345 m/s.
_____Hz

(b) What frequency does she receive after the ambulance has passed?
_____ Hz

Expert Solution

a) When ambulance is approaching the person the frequency increses and this can be calculate using below formula.

b) when ambulance is passing away from person then frequency heared by person decreses and this frequency can be find using below formula.
