Three glass cylinders of equal height $\mathrm{H}=30 \mathrm{~cm}$ and same refractive index $\mathrm{n}=1.5$ are placed on a horizontal surfaces shown in figure. Cylinder I has a flat top, cylinder II has a convex top and cylinder III has a concave top. The radii of curvature of the two curved tops are same ( $\mathrm{R}=3 \mathrm{~m}$ ). If $\mathrm{H}_1, \mathrm{H}_2$ and $\mathrm{H}_3$ are the apparent depths of a point X on the bottom of the three cylinders, respectively, the correct statement(s) is/are
