13.4 Images Formed by Lenses

A horizontal line represents the principal axis. A thin converging lens is situated vertically at the center of the axis, represented by a vertical line segment with outward-pointing arrowheads at both ends. On both sides of the lens along the principal axis, tick marks are labeled F at distance f and 2F at distance 2f. An upright arrow representing the object stands on the principal axis to the left of the lens at a distance of 3f from the center, labeled Object. No ray paths, back-extensions, or image representations are shown. No other labels, lines, text, or axes appear.
Object placed at distance 3f from a thin converging lens.
An object is placed at a distance \(d_o = 3f\) to the left of a thin converging lens with focal length \(f\). Which of the following correctly pairs the resulting image distance \(d_i\) with the path of a light ray that travels parallel to the principal axis before reaching the lens?
