Rainbows as mathematical functions

[edit]

Newton discovered that white light can be split into rainbows, but ranbows can also be described as 3 sinus functions phase shifted from each other by 2/3 π.


If the sinus functions above are used as the combined color intensity of red, green, and blue we get the rainbow below.
