A clear glass light bulb is placed 0.750 m from a convex lens having a 0.500 m focal length, as shown in Figure 25.33. Use ray tracing to get an approximate location for the image. Then use the thin lens equations to calculate

(a) The location of the image and

(b) Its magnification. Verify that ray tracing and the thin lens equations produce consistent results.

Strategy and Concept

Since the object is placed farther away from a converging lens than the focal length of the lens, this situation is analogous to those illustrated in Figure 25.31 and Figure 25.32. Ray tracing to scale should produce similar results for d_i;. Numerical solutions for d_i; and m can be obtained using the thin lens equations, noting that d_o = 0.750 m and f = 0.500 m.
