| Question | Answer |
| Intensity | The rate at which energy flows through a unit area perpendicular to the direction of wave motion. For light it is the brightness. |
| Angle of Incidence | The angle between an incoming ray and a line that is normal to the striking surface. |
| Polarization | Waves in which the direction of vibration is the same for all waves. |
| Dispersion | The process of using a prism to separate light into its component wavelengths. |
| Electromagnetic Spectrum | The complete range of electromagnetic radiation. |
| Specular Reflection | The bouncing back of a light ray off of a smooth surface. |
| Focal length | The distance between the focal point and the lens or mirror. |
| Diffuse Reflection | The bouncing back of a light ray off of a rough surface. |
| Focal Point | The point where light rays meet after reflecting off of a curved mirror or refracting through a lens. |
| Lens | A transparent object that refracts light rays, causing them to converge or diverge, to create an image. |
| Diffraction | The spreading of waves into a region behind an obstruction. |
| Object distance (do) | The distance between an object and a lens or mirror. |
| Refraction | The bending of a wave as it passes at an angle from one medium to another. |
| Real Image | An image formed where light rays that have been reflected or refracted, converge. |
| Virtual Image | An image formed where light rays that have been reflected or refracted, appear to converge only. |
| Concave | A surface that is curving inward. |
| Convex | A surface that is curving outward. |
| Ray diagram | A model used to predict image formation. |
