Question

2. A camera has a single converging lens with a fixed focal length f. (a) How far should the lens be from the film in order to focus an object that is infinitely far away (namely the incoming light rays are parallel with the principal axis of the system) (b) How far should the lens be from the film to focus an object at a distance of 2f in front of the lens? (c) What is the magnification of the image in part (b)? (d) Is the image in part (b) real or virtual? (e) Is the image in part (b) inverted? (f) If the camera can focus on objects at infinity and the lens can only move a distance f/2, what is the minimum distance at which an object can be focused? aperture ring shutter speed control lens film shutter focusing ring

    To focus a camera on objects at different 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 = 440 mm) is to be focused on an object located first at a distance of 3.5 m and then at 50.0 m. Over what distance must the lens be movable?
