Blue light, like the other colors of light, comes from white light, which
comes from the sun. To quote the Snack: "The sun produces white light,
which is made up of light of all colors: red, orange, yellow, green, blue,
indigo, violet. Light is a wave, and each of these colors corresponds to a
different frequency, and therefore wavelength, of light. The colors in the
rainbow spectrum are arranged according to their frequency: violet,
indigo, and blue light have a higher frequency than red, orange, and
yellow light. When the white light from the sun shines through the
earth's atmosphere, it collides with gas molecules. These molecules
scatter the light. The shorter the wavelength of light, the more it is
scattered by the atmosphere. Because it has a shorter wavelength, blue
light is scattered ten times more than red light."
