11. (a) Suppose one end of the object is a distance p from the mirror and the other end is a distance p + L . The position i 1 of the image of the Frst end is given by 1 p + 1 i 1 = 1 f where f is the focal length of the mirror. Thus, i 1 = fp p f . The image of the other end is located at i 2 = f ( p + L ) p + L f , so the length of the image is L 0 = i 1 i 2 = fp p f f ( p + L ) p + L f = f 2 L ( p f )( p + L f ) . Since the object is short compared to
