Articles relating to the [[visible spectrum]],  the portion of the [[electromagnetic spectrum]] that is [[visual perception|visible]] to the [[human eye]]. [[Electromagnetic radiation]] in this range of [[wavelength]]s is called '''visible light''' or simply [[light]]. A typical [[human eye]] will respond to wavelengths from about 380 to 740 [[nanometers]]. In terms of frequency, this corresponds to a band in the vicinity of 430–770 [[Hertz#SI prefixed forms of hertz|THz]].
