تاريخ الضوء
The human eye has the ability to respond to all the wavelengths of light from 400-700 nm
[The visibility of the ultraviolet to the wave length of 3130] This can be extended to a range of 310 to 1,050 nm under artificial conditions
; Goyal, Madhuri 1 January 2000 A continuous 1064 nm laser source appeared red, but a 1060 nm pulsed laser source appeared green, which suggests the presence of second harmonic generation in the retina
