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).
What is the range of frequencies on the visible light spectrum. This visible light region consists of a spectrum of wavelengths that range from approximately 700 nanometers (abbreviated nm) to approximately 400 nm. Expressed in more familiar units, the range of wavelengths extends from 7 x 10-7 meter to 4 x 10-7 meter. This narrow band of visible light is affectionately known as ROYGBIV.
