| Reflection | when light bounces back off an object. |
| Absorption | the transfer of energy carried by light waves to particles of matter. |
| scattering | the release of light energy by particles of matter that have absorbed energy. |
| refraction | when light is bent because it enters a new medium. |
| give ex. of reflection | mirror |
| give ex. of absorption | flashlight dims |
| give ex. of scattering | light is scattered which allows you to see objects out of the beam |
| give ex. of refraction | straw in cup of water. |
| order of electromagnetic spectrum | gamma rays, x rays, ultra violet rays, visible light, infrared waves, microwaves, radio waves. |
| The law of reflection | the angle of incidence equals the angle of reflection. |
| opaque | blocks all photons |
| translucent | allows some photons to pass |
| transparent | allows photons to pass by. |
