| visible light | The part of the EM spectrum human eyes can see |
| primary colors | The three colors of light that can be mixed to produce all possible colors. |
| gamma rays | The EM waves with the highest frequencies |
| radio waves | The EM waves with the longest wavelengths, the lowest frequencies, and lowest energies |
| transmission | The passage of an EM wave through a medium. |
| Electromagnetic wave | The disturbance that transfers energy through a medium. |
| infrared light | The type of EM wave most often associated with heat. |
| scattering | The spreading out of light rays in all directions as a result of reflection and absorption by particles. |
| x-rays | The EM wave that passes through soft tissues of the body but the bone is filtered out. |
| primary pigments | The colored materails that can be mixed to produce the entire color spectrum |
| radiation | The transfer of energy in the form of EM waves |
| bioluminescence | The production of light by living organisms |
| prim | A tool used for refraction of wavelengths to make white light |
| microwave | The EM waves that are used in radar and cell phones |
| polarization | Light waves that travel in the same direction |
| absorption | The disappearance of a wave into a medium |
| luminescence | The production of light without high temperature |
| incadescence | The production of light at high temperatures |
| electromagnetic wave | a disturbance that transfers energy through a field |
| radiation | the transfer of energy in the form of electromagnetic waves |
