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. |
