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

Let us take the speed of light in vacuum is c , speed of light in glass is v g , and the speed of light in water is v w . Refractive index of glass, μ g = c v g = 3 2 Refractive index of water μ w = c v w = 4 3 Relative refractive index is the ratio of speed of light in one medium to speed of light in second medium. Refractive index of glass with respect to water, μ g μ w = c v g c v w ⇒ v w v g = 3 2 4 3 = 9 8 = 1 . 12
