Question

the refractive index of glass with respect to air is 3/2 and the refractive index of water with respect to air is 4/3.what will be the refractive index of glass with respect to water

Answer 1

Refractive index of glass w.r.t air

μ_ice = 3/2

Refractive index of water w.r.t air

μ_water = 4/3

Refractive index of glass w.r.t. water

μ = (3/2)/(4/3) = 9/8.
