Suppose a student is looking closely at an object inside a container containing a liquid of refractive index 1.3, as indicated in the figure. The container measures l=57 cm and has two spherical caps. The left cap with a radius of |13 cm| is a silvery surface and the right cap with a radius of |28 cm| refract light. The object is located at the center of curvature of the left sector.  At a distance of d=21 cm the student is located to observe the object. The student has a visual problem, and wears thin glasses with a refractive index of 1.9 and radii of |72 cm|. Find the position of the image of the reflection of the object in the silver cap E and then refracted on the surface S. Determine the power in Diopters for the thin lens the student wears and the distance in cm at which the image of the object is formed when its rays are reflected by the silver cap E, refracted at S and finally pass through the lens L
