Red light is a part of the electromagnetic spectrum with wavelengths typically ranging from approximately 650 nm - 700 nm (or equivalently, 6200 Å - 7500 Å). This places it at the longer-wavelength end of the visible spectrum. The longer wavelength and associated lower frequency distinguish red light from other colors in the visible spectrum.
