It light hit smooth shiny surface like a mirror , it is reflected. The angle between an incoming light ray and a surface equals the angle between the reflected light ray and the surface.

Mirrors that curve in on the shiny side. Concave Mirrors Mirrors that curve in on the shiny side.

Mirrors that curve out on the shiny side. Convex mirrors Mirrors that curve out on the shiny side.

Polarization When materials only allow one direction of light waves to pass through them the effect is called polarization.
