I believe that there is a spectrum of light in which we can see. When the white light enters the prism, it is refracted and bends into the visible light we can see of the spectrum.
The reason we always see the spectrum in the same order is because it is how our brain perceives it. Animals could see it in a different order, etc. This is just how the human brain sees it.
When light passes into the prism glass it slows down and it bends. The color red is not as bent the same way as the color violet is bent. When the colors come out of the prism, each color is bent in a different way and in a different quantity.
