You combine two thin lenses by placing them in contact so that their axes coincide, forming what is called a compound lens. The focal lengths of the lenses are 26.9 cm and –59.9 cm, respectively. Find the focal length of this compound lens. focal length: cm Does this compound lens act as a diverging lens, as a converging lens, or it cannot be determined? converging cannot be determined diverging O O
