The critical angles for light of color a and b in crown, Ask an Expert

Academics

The critical angles for light of color "a" and "b" in crown glass are respectively 40.0757^oand 40.3604^o.

(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)
