| visible light | the part of the EM spectrum human eyes can see |
| primary colors | red, blue, and green that can be produced to make all possible colors |
| gamma rays | EM waves with the highest frequencies |
| radio waves | EM waves with the longest wavelengths, lowest frequencies, and lowest energies |
| transmission | The passage of an EM wave through a medium |
| EM wave | a disturbance that transfers energy through a field |
| infrared light | EM wave associated with heat |
| scattering | The spreading out of light in all directions as a result of reflection and absorption by particles |
| x-rays | EM wave that passes through soft tissues of the body but is filtered out by bone. |
| primary pigments | cyan, yellow, and magenta |
| radiation | the transfer of energy in the form of EM waves |
| bioluminescence | the production of light by living organisms |
| prism | the tool that uses refraction to separate the wavelengths that make up white light |
| microwave | EM waves that are used in radar and cell phones |
| polarization | a quality of light in which all of its waves vibrate in the same direction |
| absorption | the disappearance of a wave into a medium |
| UV light | EM waves that can burn the skin |
| luminescence | Production of light at without high temperatures |
| fluorescence | Absorption of UV light and given off as visible light |
| EM spectrum | The range of frequencies that include radio waves all the way to gamma rays. |
| The production of light from high temperatures | incadescent |
