A camera with a telephoto lens f 2200mm is to be focused

Reference no: EM13617077

To focus a camera on objects at different distances, the converging lens is moved toward or away from the film, so a sharp image always falls on the film. A camera with a telephoto lens (f = 220.0mm) is to be focused on an object located first at a distance of 3.5 m and then at 45.0m. Over what distance must the lens be movable?
