To focus a camera on objects at dissimilar distances

Reference no: EM13657787

To focus a camera on objects at dissimilar distances, the converging lens is moved toward or away from the image sensor, so a sharp image always falls on the sensor. A camera with a telephoto lens (f= 200.0mm) is to be focused on an object located first at a distance of 3.5m and then at 50.0m. Over what distance should the lens be moveable?
