Question

If the refractive index of glass
with respect to air is 3/2 , what
is the refractive index of air with
respect to glass?​

Answer 1

Answer:

Given

R.I of glass = $\frac{3}{2}$ - (1)

Then, the refractive index of air w.r.t glass will be the reciprocal of the given equation (1)

Refractive index of air with respect to glass = $\frac{2}{3}$
