Question

Refractive index of glass w.r.t air is3/2.the refractive index of air w.r.t glass is

Answer 1

Hey dear ur answer ☜☆☞⌐╦╦═
2/3 reciprocal of 3/2 because in refractive index the no. are reciprocal
Hope it help you dear ☜☆☞⌐╦╦═─

Answer 2

Refractive index of air =1

So

the refractive index of air w.r.t. water

=1/(3/2)

=2/3
