Question

If the asbolute reflective index of 1.5 and that of water is 4/3, find the refractive index of water with respect to glass.

Answer 1

refractive index of glass 1.5= 3/2
refractive index of water=4/3
refractive index is ratio of two mediums
therefore refractive index of water with respect to glass= 4/3/(3/2)=8/9
