Three glass cylinders of equal height H = 30 cm and same refractive index n = 1.5 are placed on a horizontal surface as shown in figure. Cylinder I has a flat top, cylinder II has a convex top and cylinder III has a concave top. The radu of curvature of the two curved tops are same (R = 3 m). If $$H_1, H_2$$ and $$H_3$$ are the apparent depths of a point_X on the bottom of the three cylinders, respectively, the correct statement(s) is/are:
