Question

The refractive index of the medium M in the diagram above is

Options

A) 1/√3

B) 2√3

C) √3

D) 2/√3


The correct answer is C.

Explanation:

From the above diagram ; ? = 90o - 30o = 60o
v = 90 - 60 = 30
∴ refractive index = (sin ?)/(sin v) = (sin 60o / sin 30o) = √3/2/1/2
= √3/2 x 1/2
= √3

  • From the above diagram ; ? = 90o - 30o = 60o
    v = 90 - 60 = 30
    ∴ refractive index = (sin ?)/(sin v) = (sin 60o / sin 30o) = √3/2/1/2
    = √3/2 x 1/2
    = √3
