What is the refractive index of a medium when the light strikes the medium after traveling through air at an angle of 23.3° and the refracted angle is 14.6°?

Answer : Refractive index, n = 1.57

Explanation :

It is given that,

The refractive index of a medium when the light strikes the medium after traveling through air at an angle of 23.3° and the refracted angle is 14.6°.

Incident angle,

Reflected angle,  

The refractive index of a medium is given by using Snell's law :

So, the refractive index of the medium is 1.57

Hence, this is the required solution.

do you have a formula possibly
