Assuming they are all able to hear the police siren, the person who hears it at the highest pitch is: E. You.

Given the following data:

  • Speed of sports car = 80 m/s.
  • Speed of police car = 90 m/s.

What is Doppler effect?

Doppler effect can be defined as the change in frequency of a wave with respect to an observer that is in motion and moving relative to the source of the wave.

This ultimately implies that, Doppler effect is the change in wave frequency due to the relative motion (change in speed) that is existing between a wave source and its observer.

In this scenario, the person who hears the police siren at the highest pitch is you because you're not in motion (static).
