A dedicated sports car enthusiast polished the inside and outside surfaces of a hubcap that is a section of a sphere. When he looks into one side of the hubcap, he sees an image of his face 30.0cm in back of it. He then turns the hubcap over, keeping it the same distance from his face. He now sees an image of his face 10.0cm in back of the hubcap. How far is his face from the hubcap? What is the magnitude of the radius of curvature of the hubcap?

Object O1 is 15.0cm to the left of a converging lens with a 10.0cm focal length. A second lens is positioned 10.0cm to the right of the first lens and is observed to form a virtual image at the position of the original object O1. What is the focal length of the second lens? What is the overall magnification of this system? What is the nature of the final image?

Two converging lenses having focal lengths of f1=10.0cm and f2=20.0cm are placed d=50.0cm apart. The final image is to be located between the lenses, at the position x=31.0cm. How far to the left of the first lens should the object be positioned? What is the overall magnification to the system? Is the final image upright or inverted?
