To focus a camera on objects at different distances, the converginglens is moved toward or away from the image sensor, so a sharpimage always falls on the sensor. A camera with a telephotolens (f = 440 mm) is to befocused on an object located first at a distance of 3.5m and then at 50.0 m. Over what distance must the lens be movable?
