A thin converging lens has focal length ff. A candle of the same height is placed on the optical axis at three different distances: 3ff, 2ff, and 1.5ff from the lens. Rank the absolute values of the image heights produced in these three cases from largest to smallest, and briefly justify your ranking without performing numerical calculations.
