Light is electromagnetic energy. It consists of photons that emanate from a source, travel in a waveform, and move in a linear direction until something acts on them to alter their path of travel. The distance measured between two consecutive crests of the waveform characterizes the wavelength of the photon. Photons that have wavelengths from approximately 400 nm (violet) to 750 nm (red) are discriminated as colors by the optical detectors of our eyes. Wavelengths in the region of 100 to 400 nm are referred to as ultraviolet (UV), and those with wavelengths longer than 750 nm are referred to as infrared (IR).
