I was reading about how a plane mirror reflects light and would like confirmation I have the right theory. It says that the metal coating of a mirror is a conductor in electrostatic equilibrium which means the electric field is zero. As the electromagnetic wave hits the mirror the electrons re-arrange themselves to keep the electric field zero. The only way to do this is reflect the light back. If we were to set up some kind of situation so as to induce a current on the surface of the mirror (by connecting some kind of power source) what would then happen to the incoming light since we would now have an electric field. My maths is not brilliant so please don't throw lots of equations at me.
