Question
A light ray travelling in air is incident vertically on one face of a right angled prism with a refractive index μ = √3 as shown in the figure and the ray follows the path shown in the figure. If θ = 60o and the base of the prism is horizontal and silvered, what is the angel φ made by emergent ray with the normal to the right face of the prism ?
Options
A.0o
B.30o
C.sin-1 
D.none of these
