White light is really a collection of all colors. Light, and therefore colors,
are made up of a flow of tiny particles (photons) that move in waves.
When they meet the face of the prism they are all at the same
inclination, but as they pass through the prism, the colors are bent
(refracted) at different angles because each has a different wavelength.
Red, which has less energy, bends the least. Violet, which has more
energy, bends at the greatest angle compared to the beam of original
white light. All the others undergo angle deviations somewhere between
red and violet.
Breaking down white light into the colors of the rainbow
means making the
spectrum of white light. The colors
which humans can see ar
e called the
visible spectr

.
There are seven colors in the visible spectrum: red, orange,
yellow, green, blue, indigo, and violet.
