The perception of each color we see is based on a different wavelength of this radiation, with red (740 nm) being the longest wavelength we can see and violet (380 nm) being the shortest (Figure 11.1):

Artificial light mimics these wavelengths of the Sun. All the color that we see with our eyes is light either reflected off surfaces or emitted by a light source.
The retina in our eyes is most...
