Question

Find angle of refraction at A=60° if refractive index of the material of the sphere is√3.

Answer 1

Heya !!!

This is your answer.....

Given -----
Angle of incidence = 60°.

Refractive Index of Sphere = √3.

We know that ....
Refractive Index = Sine (Angle of incidence)/Sine (Angle of refraction).
{Sin 60° = √3/2}

√3 = Sin 60/Sin r.
Sin r × √3 = √3/2
Sin r = 1/2.

As Sin 1/2 = 30°....
So angle of refraction is 30°.
Hope it helpsss....
