| Question | Answer |
|---|---|
| Spectrum | For sunlight and other white light, the spread of colors seen when the light is passed through a prism or diffraction grating. In general, the spread of radiation by frequency, so that each frequency appears at a different position. |
| White Light | Light, such as sunlight, that is a combination of all the colors. Under white light, white objects appear white and colored objects in their individual colors. |
| Pigment | A material that selectively absorbs colored light. |
| Additive Primary Colors | Red, blue, and green light. These colors when added together produce white light. |
| Complementary Colors | Two colors of light beams that when added together appear white. |
| Subtractive Primary Colors | The colors of magenta, yellow, and cyan. These are the three colors most useful in color mixing by subtraction. |
| Scattering | A process in which sound or light is absorbed and remitted in all directions. |
| Excited State | A state with greater energy than an atom's lowest state. |
| Spectroscope | An instrument used to separate the light from a hot gas or other light source into its constituent frequencies. |
| Line Spectrum | A pattern of distinct lines of color, corresponding to particular wavelengths, that are seen in a spectroscope when a hot gas is viewed. |
