Question

refractive index of water with respect to air is 4/3. what is the refractive index of air with respect to water?​

Answer 1

Explanation:

Given,

The refractive index of water with respect to air is 4/3.

To find,

The refractive index of air with respect to water.

we know, refractive index of A with respect to B = μ_A/μ_B

so, refractive index of water with respect to air = μ_water/μ_air

and refractive index of air with respect to water = μ_air/μ_water

now refractive index of water with respect to air × refractive index of air with respect to water = μ_water/μ_air × μ_air/μ_water = 1

⇒4/3 × refractive index of air with respect to water = 1

⇒refractive index of air with respect to water = 3/4
