Question

If reflection index of glass wrt air is 3/2 then what will be the refractive index of air wrt glass.

Answer 1

the refractive index of glass with respect to air is 3/2.the rf of air is 1.333.but it is taken approximately1.then the refractive index of air with respect to glass is 2/3.

Answer 2

refractive index of air wrt glass.

=refractive index of air/refractive index of glass.

=1/(3/2)

=2/3
