Luis is nearsighted. To correct his vision, he wears a diverging eyeglass lens with a focal length of -0.50 m. When wearing glasses, Luis looks not at an object but at the virtual image of the object because that is the point from which diverging rays enter his eye. Suppose Luis, while wearing his glasses, looks at a vertical 14-cm-tall pencil that is 2.0 m in front of his glasses.
