| Refraction | The bending of light rays when they pass obliquely from one medium to another where the speed of light changes |
| Index of Refraction | The ratio of speed of light in a vacuum to the speed of light in a given matieral |
| Primary Rainbows | Red on the top and violet on the bottom |
| Secondary Rainbows | Violet on the top and red on the bottom |
| Law of Reflection | Angle of incidence equals angle of reflection |
| Plane | Upright, true size |
| Critical Angle | When angle of incidence causes angle of reflection to be 90 |
| Total Internal Reflection | When angle of incidence is greater than angle ic |
| Dispersion | The separating of light into its component colors |
| Real | Always inverted; can be projected on a screen; formed by light rays converging in front of mirror |
| Virtual | Always upright; cannot be projected on a screen; formed by light rays that seem to converge behind mirror |
