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 cm9 \mathrm{~cm}9 cm, while the planar surface (STU) acts as a mirror. This beaker is filled with a liquid of refractive index nnn up to the level QPR. If the image of a point object O\mathrm{O}O at a height of hhh (OT in the figure) is formed onto itself, then, which of the following option(s) is(are) correct?
