Answer:
The refractive index of the material is 1.28.
Explanation:
It is given that,
Refractive index of medium 1, n₁ = 1.31
Critical angle,
At critical angle rays will reflects at 90 degrees. Using Snell's law as:
At critical angle,
So, the refractive index of the material is 1.28. Hence, this is the required solution.
