| 796927365 | Ray Model of Light | Light travels in straight lines, it can only be changed when there is an obstruction in its path, Light behaves like a wave, Light is made up of photons | |
| 796927366 | Luminous Source | An object that emits light | |
| 796927367 | Illuminated Source | An object that reflects light | |
| 796927368 | Opaque | Media that do not transmit light, but reflect light | |
| 796927369 | Transparent | Media that transmit light | |
| 796927370 | Translucent | media that transmit light, but do not permit objects to be seen clearly through them | |
| 796927371 | Speed of light | travels at 300,000 kilometers per second | |
| 796927372 | Law of Reflection | Light gets reflected from a surface at the same angle it hits it. | |
| 796927373 | Specular reflection | The light only reflects in one direction | |
| 796927374 | Diffuse Reflection | The light is scattered in different directions | |
| 796927375 | White | A mixture of the three primary colors | |
| 796927376 | Primary Colors | Red, Blue, Green | |
| 796927377 | Secondary Colors | Magenta, Cyan, Yellow (the combination of two primary colors mixed together) | |
| 796927378 | Complementary colors | Blue and yellow, red and Cyan, Green and magenta (two colors that can be combined to make white) | |
| 796927379 | Color scale | Red is the least frequent, violet is the most frequent | |
| 796927380 | Dispersion | the amount an electromagnetic wave refracts while traveling through a medium | |
| 796927381 | focal point | the point at which initially different parraell rays of light meet after passing through a convex lens, or reflecting from a concave | |
| 796927382 | focal length | is a measure of how strongly the system converges or diverges light | |
| 796927383 | Total internal reflection | When exceeding the critical angle, for that material, the ray will reflect internally within the material | |
| 796927384 | Refraction | The process of speed change while traveling through a different medium. | |
| 796927385 | Photoelectric Effect | When light incident on certain metallic surfaces causes electrons to be emitted from those surfaces | |
| 796927386 | Convex Mirror | a mirror where the sides are bent outwards | |
| 796927387 | Concave Mirror | a mirror where the sides are bent inwards | |
| 796927388 | Shadow | an area where light is blocked | |
| 796927389 | Photon | a small quantity of light. A short packet of a wave | |
| 796927390 | electron | negatively charged particle in an atom | |
| 796927391 | Intensity | how photons per second are produced or absorbed | |
| 796927392 | Photo luminance | photometric measure of the luminous intensity per unit area of light travelling in a given direction. |
