| electromagnetic wave | wave that does not require a medium |
| electromagnetic spectrum | the entire range of electromagnetic waves |
| reflection | bouncing back of a wave after it strikes an object |
| law of reflection | states that the angle of incidence is equal to the angle of reflection |
| absorption | transfer of energy carried by light waves to particles in matter |
| scattering | release of light energy by particles of matter that have absorbed extra energy |
| transmission | passing of light through matter |
| pigment | gives a substance its color by absorbing some colors and reflecting others |
| refraction | bending of a wave |
| lens | curved transparent object that refracts light |
| convex lens | lens is thicker in the middle than at the edges |
| concave lens | lens is thinner in the middle than at the edges |
| visible light | narrow band on the EM spectrum that humans can see |
| transmit | to send from one thing to another |
| incidence | point when light meets a surface |
