An object is placed 10 cm in front of a lens, A; details of the image are given below. The process is repeated for a different lens, B.
Lens A real, inverted, magnified and at a great distance.
Lens B real, inverted and same size as the object.
Estimate the focal length of each lens and state whether it is converging or diverging.
Now I've figured that both lenses are converging as well as the focal length of lens B is 5 cm. But I couldn't get the focal length of the first lens, A.
Would you mind helping me figure it out?
