Question

An object $O$ is viewed normally through a hemisphere of refractive index $\mu$ and radius $R$ in two different situations $\boldsymbol{A}$ and $\boldsymbol{B}$, as shown in figure. If $s_A$ and $s_B$ be the distances through which the object $O$ appears to be lifted in Cases $\boldsymbol{A}$ and $\boldsymbol{B}$, respectively, then

$s_A=O$, because all the rays are radial rays. $s_B=R\left(1-\frac{1}{\mu}\right)$
