A clear sheet of polarizing material is placed on a second, similar sheet so that their polarizing axes make an angle of 30∘ with each other. The ratio of intensity of emerging light to incident unpolarized light is:.
A) 1:4
B) 1:3
C) 1:2
D) 3:4
E) 3:8

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
