A side-view schematic of a composite thin biconvex lens mounted vertically on a horizontal principal axis. The upper half of the lens is shaded light gray and labeled n_1 = 1.5. The lower half of the lens is shaded medium gray and labeled n_2 = 1.7. A horizontal dashed line represents the central principal axis passing through the geometric center of the lens. To the left of the lens, an upright vertical arrow labeled Object stands on the principal axis at a distance d_o from the lens center. No light rays, images, or focal points are drawn. No other labels, lines, text, or axes appear.
Composite lens with upper and lower halves made of different refractive indices.
A thin converging lens is fabricated from two different transparent materials joined along the horizontal principal axis. The upper half of the lens has an index of refraction \(n_1 = 1.5\), while the lower half has an index of refraction \(n_2 = 1.7\). Both halves share the exact same surface curvatures. An illuminated object is placed on the principal axis at a distance \(d_o\) from the lens such that \(d_o\) is greater than the focal length of either half. Which of the following claims and justifications correctly describes the image or images formed by this composite lens?
