Application +4 | -1

The angle of incidence for a ray of light at a refracting surface of a prism is

{45^\mathrm{o}}

. The angle of prism is

{60^\mathrm{o}}

. If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are:

View answer and explanation

Correct option: B

{30^\mathrm{o}};\,\sqrt 2

Option B (

{30^\mathrm{o}};\\,\sqrt 2

) is correct because the angle of minimum deviation and refractive index are calculated using the given angle of incidence and prism angle.
