Question: A beam of light in air is incident upon a stack of four flat transparent materials with indices of refration 1.20,1.40, 1.32, 1.28. If the angle of incidence for the beam on the first of the four materials is 60 degrees, what angle does the beam make with the normal when it emerges into the air after passing through the entire stack?
