This question bothered me for some time.
From what i have seen in textbooks, dispersion occurs as soon as white light passes from air into a glass prism, but why not for a glass block, assuming that the angle of incidence is the same?
The standard answer for why dispersion happens in glass prism is because of the different speeds of different coloured light in glass, so why is there a difference between a glass block and a glass prism?
