Light and human
“Light” refers to the electromagnetic waves visible to the human eye.
In addition to visible light, sometimes, by extension, the word “light” is used to refer to other electromagnetic waves such as those in the infrared and ultraviolet spectrums.
1) How does the eye see light?
2) The colour of light and its influence on behaviour
3) Light and vision
4) Lighting
As a preliminary, it will be recalled that if it is diffracted by rain, daylight creates a rainbow. This phenomenon illustrates that daylight (which is white) is the sum of all the colours. To the contrary, black is the absence of colour.
Consequently, black and white are not colours.
