>>14282343Faraday cages work because radio waves DO interact with charges in the metal of the cage. The electric field of the radio pulse sends these electrons into motion, which generate a separate magnetic field in accordance with Maxwell's equations, which push other electrons in the opposite motion, which ends up blocking the path of the wave. (basically.)
light works EXACTLY the same way, except for the fact its frequency is about a million times greater than radio waves.
