Question

The refractive index of water to air is 4/3 and the refractive index from medium to air is 3/2 find the refractive index from water to the medium.

Answer 1

Answer:

Refractive index of water w.r.t air = 4/3

Refractive index of glass w.r.t air = 3/2

Therefore, refractive index of water with respect to glass

= Refractive index of water / Refractive index of glass

= (4/3) / (2/3)

? = 8 / 9

Also, refractive index of glass with respect to water

= Refractive index of glass / Refractive index of water

= (3/2) / (4/3)

? = 9/8
