Question

Refractive index of water and glass are 4/3 and 3/2 respectively. A light ray travelling in water is incident on water glass interface at 30 degree. The angle of sine of angle of reflection is
1) 4/9
2) 8/9
3) 9/16
4) 2/3​

Answer 1

Explanation:

We are also given that the refractive index of water and glass are 43 and 32 respectively. Here, μ2= The refractive index of the medium that ray of light travels to. So, when the ray of light is incident on the water-glass interface at 30∘, the angle that the refracted ray makes with the normal is 0.444.
