A prism refracts light.
A grating diffracts light.

White light is not made up of seven colors. The number seven was invented by Newton because seven is a lucky number. The number of colors you can see varies from person to person.

If you say blue light is diffracted less because its short wave then why is it diffracted the most in a prism?
