Question

Refractive index of water with respect to air is 1.33,what is refractive index of air with respect to water

Answer 1

Refractive Index = 1/1.33
0.75

Answer 2

The “Refractive index of air” with “respect to water” is 0.75

Given:

The “Refractive index of water” with “respect to air” = 1.33

To find:

The “Refractive index of air” with “respect to water” =?

Solution:

$n = 1.33$

$\text{Refractive index}=\frac{1}{n}$

$\text{Refractive index}=\frac{1}{1.33}$

$\therefore \text { Refractive index }=0.75$

The “Refractive index” is defined as the ratio of "velocity of the light” in a vacuum place to the “velocity in a specific medium”.
