Question
Let the x - z 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
is incident on the plane of separation. The angle of refraction in medium 2 isOptions
A.45o
B.60o
C.75o
D.30o
Solution
Normal to the plane is z - axis
cosθ1 =
⇒ θ1 = 60
μ1 sinθ1 = μ2 θ2 ⇒
⇒ θ2 = 45o
cosθ1 =
⇒ θ1 = 60 μ1 sinθ1 = μ2 θ2 ⇒
⇒ θ2 = 45o Create a free account to view solution
