Question

In the diagram shown above $n_{1}, n_{2}$ and $n_{3}$ are refractive indices of the media $1, 2$ and $3$ respectively. Which one of the following is true in this case?

[ $1$ Mark ]

Open in App

Solution

Since $θ_{2} < θ_{1}$ , which means medium 2 is denser than medium 1. Also, $θ_{3} < θ_{2}$ which imply that medium 3 is dener than the medium 2.

$θ_{3} < θ_{2} < θ_{1}$

$\Rightarrow n_{3} > n_{2} > n_{1}$

$\Rightarrow n_{3} > n_{1}$
