A glass beaker has a solid, plano-convex base of refractive index 1.60, as shown in the figure. The radius of curvature of the convex surface (SPU) is $9 \mathrm{~cm}$, while the planar surface (STU) acts as a mirror. This beaker is filled with a liquid of refractive index $n$ up to the level QPR. If the image of a point object $\mathrm{O}$ at a height of $h$ (OT in the figure) is formed onto itself, then, which of the following option(s) is(are) correct?

A
It will deflect up by an angle $\tan ^{-1}\left[\frac{\left(n_2^2-n_1^2\right) d}{2 h}\right]$.
B
It will deflect up by an angle $\tan ^{-1}\left[\frac{\left(n_2-n_1\right) d}{h}\right]$.
C
It will not deflect.
D
The deflection angle depends only on $\left(n_2-n_1\right)$ and not on the individual values of $n_1$ and $n_2$.

Three plane mirrors form an equilateral triangle with each side of length $L$. There is a small hole at a distance $l>0$ from one of the corners as shown in the figure. A ray of light is passed through the hole at an angle $\theta$ and can only come out through the same hole. The cross section of the mirror configuration and the ray of light lie on the same plane.
