Q.A police siren passes you with a frequency of 5000 Hz. Which correctly describes the sound wave after the police car passes you? The speed of sound is 340 m/s.

(a) siren wavelength of 0.0068 meters, frequency you hear = less than 5000 Hz

(using doppler's effect)

What is the Doppler effect?

Doppler effect is the apparent difference between the frequency at which sound or light waves leave a source and that at which they reach an observer, caused by the relative motion of the observer and the wave source.

Who discovered the Doppler Effect?

Christian Johann Doppler, an Austrian mathematician, and physicist discovered the Doppler effect in 1842.
