When light hits a smooth or polished surface it "bounces" off at the same angle that it hit. Reflecting telescopes are made of concave mirrors and they have helped astronomers chart the universe because the mirrors interact with each other to magnify what is being observed.

Refraction is when light bends as it goes through glass, water and other transparent objects that are denser than air. A prism is an instrument that spreads out a ray of light into the color spectrum. A lens is another instrument that uses the light refraction, but lenses are put to more practical uses (I'm not saying that a mirror isn't practical enough.).

Welcome to the wonderful world of light, including the refraction

and reflection of light. Refraction is the bending of light when it travels

through a denser, or thicker material, such as water. Reflection is

a bit different though; when light hits a smooth or polishe

Huygens countered Newton with the wave theory. He figured he could

light slows down as it travels through a denser material than it was

Now scientists believe that the two theories complement each other. As a result the quantum theory came into being. The quantum theory says that in some ways light acts as a series of particles and in other ways acts as a wave.
