Infrared Light. Infrared (IR) light is light with lower frequency (higher wavelength) than visible light. IR light has frequencies ranging from 3*1011 to 4*1014 Hz (300 GHz to 400 THz) and wavelengths from 7.5*10-7 m to 10-3 m (750 nm to 1 mm).
Infrared radiation is the next region on the electromagnetic spectrum. We call it infrared because it's just 'below' the red part of the visible spectrum. It spans from frequencies of about 300 gigahertz to about 400 terahertz. This is the same as a range of wavelengths from one millimeter to 750 nanometers.
