The phenomenon of refraction occurs even in metals. However, the metal is a metal because it has free electrons that can move easily. A passing electromagnetic wave (light) will cause these electrons to move. Movement of electrons (a current) creates electromagnetic waves that just so happen to exactly oppose the light that caused the electron movement. The light is extinguished as soon as it passes a few dozen metal atoms.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
