You are siting outside of a coffeee shop, sipping coffee and working on your physics homework, when all of a sudden a police car approaches you with the siren on. What can we say about the speed, wavelength and frequency of the siren sound you perceive? They all stay the same as if the police car were stationary. The speed increases but the wavelength and frequency stay the same. The frequency increases but the wavelength and speed stay the same. The wavelength increases but the speed and frequency stay the same. The frequency increases, the wavelength decreases and the speed stays the same. The wavelength increases, the frequency decreases and the speed stays the same. The speed increases, the frequency decreases and wavelength stays the same.

The correct answer is The frequency increases, the wavelength decreases and the speed stays the…
