Question

The refractive index of water relative to air is $\frac{4}{3}$. Find the relative refractive index in the case of light being refracted from water to air.

Answer 1

Given,

Refrective index of the water to air is $\frac{4}{3}$

Thus the relative refrective index of light being refrected water to air,

$\frac{{\mu }_w}{{\mu }_a}=\frac{4}{3}$
