Radar Guns and Relativity

Authors: Edward G. Lake

Radar guns provide an excellent means of explaining and demonstrating some of Einstein’s Relativity theories in a fairly simple and undeniable way. Specifically, radar guns demonstrate how the speed of the emitter cannot add to the speed of the light being emitted, but the speed of the receiver/observer affects the energy of the light that is returned to the gun. In practice, this directly conflicts with basic tenets of mathematicians who somehow believe that all motion is relative, and the properties of light will therefore always be the same for the emitter as for the receiver. A step by step analysis of how radar guns work shatters those beliefs.
