Question

if the refractive index of glass with respect to air is 3
/
2, then the refractive

index of air with respect to glass is ____ (a) 4/8 (b) 3 (c) 1/3 (d) 12
/18 ​

Answer 1

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.

My above answer written by me was wrong. The correct answer is not 8/9 but rather 9/8.

Refractive index of water wrt air= 4/3

Refractive index of glass wrt to air = 3/2

Refractive index of air wrt water = 1/(refractive index of water wrt air) = 1/(4/3) = 3/4

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