Question

Refractive index of glass 1.5 that of water is 1.3 find the refractive index water w.r.t glass

Answer 1

Answer:

   Refractive index of water with respect to glass = 0.867

Explanation:

Refractive index is the measure of the bending of the ray when it travels from one medium to another.

Given that,

   Refractive index of a glass = 1.5

   Refractive index of water = 1.3

   Refractive index of water with respect to glass = $\frac{Refractive index of water}{Refractive index of glass}$

                                                                              = $\frac{1.3}{1.5} = 0.867$
