# If the refractive index of glass for light going from air to glass is 3/2, find the refractive index of air for light going from glass to air. - Science

If the refractive index of glass for light going from air to glass is 3/2, find the refractive index of air for light going from glass to air.

#### Solution

Given:-

Refractive index of glass with respect to air=mu_g^a=3/2

Refractive index of air with respect to glass =mu_a^g=1/mu_g^a=1/(3/2)=2/3

Concept: Refractive Index
