2. Focusing Distance For a camera with a lens of fixed focal length F to focus on an object located a distance x from the lens, the film must be placed a distance y behind the lens, where F, x, and y are related by 1 1 1 y F (See the figure.) Suppose the camera has a 55-mm lens (F = 55). (a) Express y as a function of x, and graph the function. (b) What happens to the focusing distance y as the object moves far away from the lens? (c) What happens to the focusing distance y as the object moves close to the lens? F-
