Two converging lenses (f1 = 8.50 cm and f2 = 5.90 cm) are separated by 17.4 cm. The lens on the left has the longer focal length. An object stands 11.5 cm to the left of the left-hand lens in the combination. Locate the final image relative to the lens on the right. Obtain the overall magnification. Is the final image real or virtual? With respect to the original object, is the final image upright or inverted and is it larger or smaller?
