 Light is an electromagnetic wave, the wavelength range from a few nanometers (1nm = 10-9m) to about 1 millimeter (mm). Visible to human eyes is just one part we call visible light, visible light wavelength range of 380nm ~ 780nm, the wavelength of visible light from long to short is divided into red, orange, yellow, green, green, blue, violet wavelength than violet known as ultraviolet light, short wavelength infrared light called infrared light. Infrared light are usually people will be divided into near and far-infrared of three parts. Near-infrared refers to the wavelength of 0.75 to 3.0 microns; refers to the infrared wavelength of 3.0 to 20 microns; refers to far-infrared wavelengths of 20 to 1000 microns. Infrared lights have different power and 715,830 nM for two wavelengths, the wavelength of the different distance and effect of infrared lighting: 715nM of infrared light due to the distance of the lighting, the effect, but will produce a red storm (home digital camera complement of light is this infrared light);
