| A | B |
|---|
| optics | study of how light behaves |
| refraction | Bending of light rays that results as light passes from one medium to another |
| lens | device that use refraction to bend light to form an image |
| prism | A device that bends different frequencies of light |
| convex lens | thicker in the middle, thinner on edges |
| concave lens | thinner in the middle, thicker on the edges |
| sterooeoscopic vision | Deals with depth perception |
| fiber optics | Light pipe the use total internal reflection to carry light and signals |
| normal | line drawn perpendicular to the surface of a mirror or any other medium |
| total internal reflection | happens when light within a material strikes the surface at an angle greater than the critical angle and reflects back |
