| radiation | the emmision of energy in the form of EM waves |
| wavelength | the distance between any two adjacent crest in a series per waves |
| frequency | # of waves produced in a given time |
| amplitude | the max distance the wave vibrates from its rest position |
| electromagnetic spectrum | the entire range of EM waves |
| reflection | occurs when light bounces off an object at the same angle and strikes the object |
| refraction | the bending of waves as they pass into a new medium |
| absorption | when light energy is transferred into a particle of matter |
| scattering | a release of light energy by particles of matter that have absorbed energy |
| diffraction | the bending of light around barriers |
| transparent | matter through which visible light is easily transmitted |
| translucent | matter transmitts light, but also scatters the light as it passes through the matter, not easliy seen |
| opaque | matter does not transmitt any light through matter cannot be seen through |
| transmission | the passing of light through matter |
| law of reflection | states that the angle of incidence is equal to the angle of reflection |
