DESCRIPTION
Problem 40504.
A photographic camera whose lens has a focal length F1 = 13.5 cm needs to photograph an object located at a distance d = 18 cm from the lens. The distance from the photographic plate to the lens is f = 27 cm. What should be the focal length F2 of the so-called attachment lens, which must be placed close to the lens in order for the image on the photographic plate to be sharp?
