Electromagnetic radiation that the human eye can see as "light" is known as visible light. Generally speaking, visible light is characterised as having wavelengths between the infrared and ultraviolet that are between 400 and 700 nanometers, or 750 and 420 terahertz, in frequency. An electromagnetic wave with a wavelength between 380 and 750 nanometers that can be seen by the human eye is referred to as light.
