In the figure shown , a point object O is placed in air on the principal axis. The radius of curvature of the spherical surfaces is `60 cm.` I is the final image formed after all reflections and refractions.

In the figure, a point object O is placed in air. A spherical boundry separates two media of radius of curvature 1.0 m. AB is principal axis. The separation between the images formed due to refraction at spherical surface is
