An object is 2 m from the front side of a 1 m focal lenth converging lens. A second converging lens with focal length 2 m is placed 1 m from the first on the opposite side from the object. Draw a ray diagram of the situation. What is the distance of the final image from the second lens? What is the magnification of the lens system? The object is now moved inward until it is 1 m from the first lens. Draw a ray diagram of the new situation. Where is the final image now? What is the new magnification?
