More quantitatively, since the diverging lens is 28 cm to the right of the converging lens, the object distance is do = 28 cm + 12 cm = 40 cm; this is the distance between the diverging lens and the image formed by the converging lens.
Focal length is the distance from the center of a lens to the point where the light rays converge and the object is in optimal focus (focal point). This is also known as the working distance of the lens. Focal length is important when the task requires using tools with the object being viewed.
