The speed of an ambulence on a highway is 34m/s. The frequency of the sound emitted by its siren is 500Hz. Calculate the frequency heard by the driver in a car travelling at 72km/r in the opposite direction, (i) before crossing and (ii) after crossing (V=340m/s)

To solve the problem, we will use the Doppler effect formula for sound. The formula for the apparent frequency \( f' \) heard by an observer when both the source and observer are moving is given by: \[ f' = f \times \frac{V + V_o}{V - V_s} \] Where: - \( f' \) = apparent frequency ...
