일반물리학 2 — Images: Problem 12

12 An object is moved along the central axis of a spherical mirror while the lateral magnification \(m\) of it is measured. Figure 34-26 gives \(m\) versus object distance \(p\) for the range \(p_a = 2.0 \text{ cm}\) to \(p_b = 8.0 \text{ cm}\). What is \(m\) for \(p = 20.0 \text{ cm}\)?
