Question

derive the relation between refractive index and of a medium and its critical angle

Answer 1

Answer:

hope it will help you

Explanation:

Snell's Law (also known as the Second Law of refraction) is applied to derive the relation between critical angle and refractive index. Hence, take a light ray having an incident angle i, refractive angle r = 90 degrees, critical angle = C and refractive index of rarer and denser medium be µa and µb respectively..
