The critical angles for light of color "a" and "b" in crown glass are respectively 40.0757o and 40.3604o.
(a) If light is incident on crown glass from air, which color "a" or "b", will be refracted more? Explain?
(b) Find angle seperating the two rays in a piece pf crown glass if their angle of incidence is 53.0000o. (Illustrate with a sketch)
