Question

If the absolute refractive indices of water and glass are 4/3 and 3/2 respectively. What is the refractive index of water with respect to glass?​

Answer 1

Answer:

If the absolute refractive indices of glass and water are 3/2 and 4/3 respectively, what is the refractive index of glass with respect to water?

here absolute refractive indices of glass ng = 3/2 and

of water is given as nw = 4/3.

Absolute Refractive Index of a medium

= Speed of light in vacuum/Speed of light in the medium

= v(vacuum)/v(medium)

Therefore,

V(vac.) / V(glass) = 3/2

and V(vac.) / V(water) = 4/3

Therefore the refractive index of glass

with respect to water = V(water)/V(glass)

={V(water)/V(vac.)} / [V(glass)/V(vac.)} = (3/4) /(2 /3) = 9/8 =1.125
