Explanation:

The decomposition of  light into colors by a prism has to do with the fact that white visible light is made up of a range of wavelengths (from 400nm to approximately 700nm) and within this range of wavelengths we find the colors we know from the rainbow (violet, indigo, blue, green, yellow, orange and red) violet at 400nm to red at 700nm.

In a prism, each wavelength travels at a slightly different speed, resulting in the decomposition of white light into the colors of the rainbow.

Colors with smaller wavelengths will travel slower in the prism than colors with larger wavelengths. So colors with larger wavelengths will not deviate as much as colors with shorter wavelengths.

Thus, the order starting with the color that is bent the least is:

This is because red travels faster in the prism than violet,  thus it does not bend as much.

the part of the wave he is travelling on is the crest
