1.5/1.12 = 1.34

Answer 2

Answer:

The absolute refractive index of water is 1.34

Explanation:

Refractive index of glass with respect to water = 1.12

We know that

$\text{Refractive index of medium 1 with respect to medium 2}=\frac{\text{Refractive index of medium 1}}{\text{Refractive index of medium 2}}$

Therefore,

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

or, $1.012=\frac{1.5}{\text{Refractive index of water}}$

or, $\text{Refractive index of water}=\frac{1.5}{1.12} =1.34$
