Question

refractive index of diamond is 2.42 and that of Glass is 1.5 calculate the critical angle for diamond glass surface​

Answer 1

Answer:

Hey mate your answer is here

Explanation:

For a light ray incident on the air-diamond surface to completely reflect back of the smallest possible angle is  

μsin i  min

=1

⟹i * min  

=sin*  −1/ (  μ 1  )

=sin  *−1 /(  2.42 1  )=24  ∘
