AP Physics 2
14.5 The Doppler Effect
An ambulance emitting a siren sound of constant frequency \(f_0\) travels at a constant speed \(v\) along a straight horizontal road. A car directly behind the ambulance travels in the same direction at the exact same constant speed \(v\). How does the frequency \(f\) of the siren sound heard by the driver of the car compare to \(f_0\), and what is the correct justification?
