| Electromagnetic wave | a wave that can travel through space or matter and consists of changinc electric and magnetic field |
| Radiation | the emmission of energy in the form of electromagnetic waves |
| Electromagnetic spectrum | the entire range of electromagntic waves |
| reflection | what happen when light or any other wave bounces off an object |
| law of reflection | the law that states that the angel of incidence is equal to the angle of reflection |
| absorption | the transfer of energy carried by light waves to particles of matter |
| scattering | the release of the light energy by particles of matter that have absorbed energy |
| refraction | the bending of wave as it passes at an angle from one medium to another |
| diffraction | the bending of waves around barriers or through openings |
| interference | a wave interaction that occurs when two or more waves overlap and bomine |
| transmission | the passing of light through matter |
| transparent | describes matter though which light is easily transmitted |
| transculent | describes matter that transmitt light but also scatter the light as it passes through the matter |
| opaque | describes matter that does not transmit any light |
| pigment | a material that gives a substance its color by absorbing some color of light and reflecting other |
