<P> The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye . Electromagnetic radiation in this range of wavelengths is called visible light or simply light . A typical human eye will respond to wavelengths from about 390 to 700 nanometers . In terms of frequency , this corresponds to a band in the vicinity of 430 -- 770 THz . </P>
