# The Refractive Indices of Glass and Water W.R.T. Air Are 3/2 And 4/3 Respectively. Determine The Refractive Index of Glass W.R.T. Water. - Physics

The refractive indices of glass and water w.r.t. air are 3/2 and 4/3 respectively. Determine the refractive index of glass w.r.t. water.

#### Solution

Given:

""_amu_g=3/2, ""_amu_w=4/3

Find: ""_wmu_g

Formula:  ""_wmu_g=(""_amu_g)/(""_amu_w)

solution: ""a_mu_g=C_a/C_g and ""_amu_w=C_a/C_w

""_wmu_g=C_w/C_g

From Formula

""_amu_g=(3/2)/(4/3)

""_wmu_g=1.12

The refractive index of glass w.r.t. water is 1.12.
