Suppose you are told that only two colors of light (X and Y) are sent through a glass prism and that X is bent more than Y. Which color travels more slowly in the prism?
The one that is bent more travels slower.
If white light is sent through a prism, the colors on the other side of the prism from the entrance side are
in that order; i.e., red at the top and violet at the bottom. Violet is bent the most; red is bent the least. So which is traveling faster?
i don't know
