Consider the following statements A and B. Identify the correct choice in the given answer A. The refractive index of the extraordinary ray depends on the angle of incidence in the double refraction.
B. The vibration of light waves acquire one sided ness of both ordinary and extraordinary rays in double refraction.

Options

A. A and B are wrong
B. A and B are correct
C. A is correct B is wrong
D. A is wrong B is correct

Answer

b

Explanation

In double refraction method both ordinary and extra ordinary rays are polarised.
The refractive index of ordinary ray is independent of angle of incidence where as refractive index of extraordinary ray depends on angle of incidence.
