일반물리학 2 — Images: Problem 90

90 An object is placed against the center of a thin lens and then moved away from it along the central axis as the image distance \(i\) is measured. Figure 34-39 gives \(i\) versus object distance \(p\) out to \(p_s = 60 \text{ cm}\). What is the image distance when \(p = 120 \text{ cm}\)?
