White light is actually composed of light having
wavelengths that vary continuously between about 400 and 700 nanometers.
Because human eyes use only three different color photoreceptors that have
broad and overlapping absorbances, the makers
of computer monitors can use only three phosphors emitting at wavelengths that
match those of peak absorbances of the photoreceptors.

If you're still in school, be sure to pay attention.  Maybe next time you'll
get it right.
