Question

The refractive index of glass with respect to air 3/2 and the refractive index of water with respect to air is 4/3. Then (a) what will be the refractive index of glass respect to water and b)what will be the refractive index of water with respect to glass?​

Answer 1

Explanation:

Refractive index of water wrt air (water n air)= 4/3

Refractive index of glass wrt air (glass n air) = 3/2

Refractive index of glass wrt water ( glass n water) = (glass n air)× (air n water) = (glass n air)× (1/water n air) = 4/3 × 2/3 = 8/9.
