Question

Let the xz - plane be the boundary between two transparent media. Medium 1 in z ≥ 0 has a refractive index of √2 and medium 2 with z < 0 has a refractive index of √3 . A ray of light in medium 1 given by the vector is incident on the plane of separation. The angle of refraction in medium 2 is

(a) 30° 

(b) 45°

(c) 60° 

(d) 75°

Answer 1

Correct Option (a) 30° 

Explanation:

As refractive index for z > 0 and z < 0 is different, xy - plane should be boundary between two media.
