Answer 2

Given:

Refractive index of water = 3/2

Refractive index of glass = 4/3

To find:

The refractive index of glass with respect to the refractive index of water.

Formula:

➝ Refractive index of glass

Refractive index of water

➝ 3/2/4/3

[3 gets multiplied to 3 and 4 gets multiplied to 2 which gives the result as 9/8]

➝ 9/8

Answer:

So, the correct option is B.) which is 9/8
