Chapter 26, Problem 114GP

(choose chapter or problem)

An arrow \(2.00 \mathrm{~cm}\) long is located \(75.0 \mathrm{~cm}\) from a lens that has a focal length \(f=30.0 \mathrm{~cm}\)

(a) If the arrow is perpendicular to the principal axis of the lens, as in Figure 26–59 (a), what is its lateral magnification, defined as \(h_{i} / h_{0}\)?

(b) Suppose, instead, that the arrow lies along the principal axis, extending from

\(74.0 \mathrm{~cm} \text { to } 76.0\) from the lens, as indicated in Figure 26–59 (b). What is the longitudinal magnification of the arrow, defined as \(L_{i} / L_{o}\)? (Hint: Use the thin-lens equation to locate the image of each end of the arrow.)
