experiment on prism...
A mixture of equal amounts of all wavelengths of light produces white light, like that from the sun or from incandescent lamps (the kind that get hot). [These light sources really produce a yellowish orange because they have more longer (red & yellow) than shorter (green & blue) wavelengths.] Isaac Newton (1642 - 1727)

demonstrated over 300 years ago that a prism breaks up white light into the spectral colors and puts the spectrum back together into white light, as Figure 3 shows.

Droplets of water do the same to make rainbows. In order of decreasing wavelength, the colors of the spectrum are: red, orange, yellow, green, blue, and violet, with blends like orange-yellow and blue-green in between.
