Question

b. If the absolute refractive indices of glass and water are 3/2 and 4/3 respectively, what is the refractive index of glass with respect to water?​

Answer 1

Step-by-step explanation:

Answer :-

Refractive index of glass with respect to water is 9/8 .

Explanation :-

We have :-

→ Refractive index of glass = 3/2

→ Refractive index of water = 4/3

________________________________

If 'n₁' and and 'n₂' are refractive indices of Medium 1 and Medium 2 respectively, then refractive index of Medium 2 with respect to Medium 1 (n₂₁) is :-

n₂₁ = n₂/n₁

________________________________

Here, n₂ = 3/2 ; n₁ = 4/3

Substituting values, we get :

⇒ n₂₁ = [3/2]/[4/3]

⇒ n₂₁ = 3/2 × 3/4

⇒ n₂₁ = 9/8
