Задача 40510.

An object with a height of h = 2 cm is placed at a distance d1 = 25 cm from a collecting lens with a focal length F1 = 20 cm. A second collecting lens with a focal length F2 = 40 cm is located at a distance l = 1.5 m from the first. The optical axes of both lenses coincide. At what distance f2 from the second lens will the image of the object be obtained after the rays pass through both lenses? What is the height H of the resulting image?
