Question

i) Light reflected at 62.7° from a gemstone in a ring is completely polarized. Can the gem be a diamond

(n = 2.419 ± 0.06)? No    

(a)At what angle (in degrees) would the light be completely polarized if the gem were in benzene

(n = 1.501)?

ii) The angle between the axes of two polarizing filters is 33.0°. By how much does the second filter reduce the intensity of the light coming through the first?
