A ray of light travels from air into another medium, making an angle of θ1 = 45.0o with the normal as in the figure below.
(a) Find the angle of refraction θ2 if the second medium is fluorite. (The index of refraction for fluorite is 1.434.)
(b) Find the angle of refraction θ2 if the second medium is crown glass. (The index of refraction for crown glass is 1.52.)
(c) Find the angle of refraction θ2 if the second medium is polystyrene. (The index of refraction for polystyrene is 1.49.)
