In a biconvex lens, the initial image was k1 = 4 times larger than the object. Then the lens was moved away from the object at a distance l = 0.4 cm, after which the image became k2 = 5 times larger than the object. Find the optical power of the lens. Both images are virtual and are at the distance of best vision from the lens.
