Radar Trap (Vehicle Speed Camera) and Speed of LighT

The principle of speed measuring instruments using microwave and laser is the same as the principle of the Doppler effect of sound. That is, in the equation, c'= fλ, in inertial frame of a moving vehicle, f of incident wave and reflected wave are the same, and c'and λ are different. In a vacuum, c'of the two waves is different (in both inertial frame of measuring instrument and inertial frame of moving object : according to emission theory).
