Question

The angle of incident of a light ray is 30° and it takes refraction with an angle 60° , find the refractive index of the medium.

Answer 1

Answer:

1/3^1/2

refractive index of the medium is sini/sinr=sin30°/sin60°=1/2/2/3^-1/2

=1/3^1/2

Answer 2

Explanation:

refractive index=sini/sinr=sin30°/sin60°=1/2×2/√3= 1/√3
