When a radio wave of frequency hits a metal, the electrons in the metal move with the same frequency and emit the radio wave of the same frequency. This is how a radio wave is reflected by a metal. A car approaching a police officer with velocity . The police officer has a radar which emits a radio wave with frequency f. The radio wave reflects from the metal of the car and the frequency of the reflected radio wave is measured by the officer's radar. 1. What is the frequency of the reflected radio wave in the frame of reference of the moving car?

2. What is the frequency of the reflected radio wave as measured by the officers radar?
