Answer 1

The refractive index of medium z with respect to medium x is 9/8.

Explanation:

The refractive index of air ,μₐ = 1.

Given;

Refractive index of medium x with respect to medium y , μ(xy) = 2/3

Refractive index of medium y with respect to medium z, μ(yz) = 4/3.

Refractive index of medium z with respect to medium x,

μ(zx) = μ(z)/μ(x) = (μz/μy)x(μy/μx).

μ(zx) = $\frac{1}{u_{yz} }x\frac{1}{u_{xy} }$

μ(zx) = $\frac{1}{4/3}x\frac{1}{2/3}$

μ(zx) = $\frac{3}{4}x\frac{3}{2}$

μ(zx) = $\frac{9}{8}$.

Refractive index of medium z with respect to medium x will be 9/8
