Compute over what distance must the lens be movable

Reference no: EM13649389

To focus a camera on objects at different distances, the converginglens is moved toward or away from the film, so a sharp image alwaysfalls on the film. A camera with a telephoto lens (f =180.0 mm) is to be focused on an objectlocated first at a distance of 3.5 m and then at 48.0 m. Over what distance must the lens be movable?
