A glass rod 96 cm long with an index of refraction of 1.6 has its ends ground to convex spherical surfaces of radii 8 cm and 16 cm. A point object is in air on the axis of the rod 18.7cm from the end with the 8 cm radius.
(a) Find the image distance due to refraction at the first surface. (Include the sign.)
(b) Find the location of the final image distance due to refraction at both surfaces.
(c) Describe the final image.
