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
-
45°
-
60°
-
75°
-
30°
Solution
A.
45°
As a refractive index for z>0 and z≤0 is different xy-plane should be the boundary between two media.
Angle of incidence,
