Mirrors-n-Lenses

Reflection and Refraction with Curved Surfaces:

Mirrors reflect light and lenses refract refract. Law of reflection - the angle of reflection will equal the angle of incidence. (The out going angle equals the incoming angle.)

Refraction - When light rays enter a medium at an angle, the change in speed causes the rays to bend, or change direction.

1. A convex mirrors reflect rays of light away from a focal point behind the mirror. || 2. A concave mirrors reflects rays of light back to a focal point. || 3. A convex lens refract light to a focal point behind the lens. || 4. A concave lens refracts light away from a focal point in front of the lens. ||
