Definition that contains wavelength
- a a metric unit of length equal to one ten billionth of a meter (or 0.0001 micron); used to specify wavelengths of electromagnetic radiation
- infrared electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves
- infrared having or employing wavelengths longer than light but shorter than radio waves; lying outside the visible spectrum at its red end
- hue the quality of a color as determined by its dominant wavelength
- ultraviolet having or employing wavelengths shorter than light but longer than X-rays; lying outside the visible spectrum at its violet end
- grating optical device consisting of a surface with many parallel grooves in it; disperses a beam of light (or other electromagnetic radiation) into its wavelengths to produce its spectrum
- angstrom a metric unit of length equal to one ten billionth of a meter (or 0.0001 micron); used to specify wavelengths of electromagnetic radiation
- fluorescence light emitted during absorption of radiation of some other (invisible) wavelength
- monochromatic (of light or other electromagnetic radiation) having only one wavelength
- polychromatic (of light or other electromagnetic radiation) composed of more than one wavelength
