A person going away from a factory on his scooter at a speedof `36 kmh^-1` listens to the siren of the factory. If the main frequency of the siren is 600 hz and a wind is blowing alongthe direction of the scooter at `36 kmh^-1`, find the main frequency as heard by the person.

Explanation

To solve the problem, we will use the Doppler effect formula for sound waves. The formula for the apparent frequency (ν') heard by an observer moving away from a stationary source is given by:

\[ \nu' = \nu \left( \frac{V - V_o}{V + V_s} \right) \]

Where:
- \( \nu' \) = apparent frequency
