3. Use graphic method to verify the position ( s' ) and size ( h ) of the image in Table 1, and determine the nature of the image: erect or inverted, enlarged or reduced. (a) Refer to Fig. 3 (a) in the lab manual, draw a converging lens with an optic axis on a sheet of white paper. The converging lens in Fig. 3 (a) can be simplified as shown in Fig. 2. Optic axis F F, Figure 2 Converging lens (b) To make a ray diagram showing the formation of the image we need to use the following data in Table 1: h, fexp , and the value of S in the row #6 of the column "Calculation" in Table 1. Note: The top row of Table 1 is row #1. (c) Make a scale drawing (use 1 mm to represent 1 cm) to locate the positions of the two focal points (Fi & F2) using the value of fexp , also locate the object position using the S value. Then, at the object position draw the object with height h using the same draw scaling. (d) Draw a ray diagram using two principal rays: Parallel ray and Central ray similar to Fig. 3 (a) in the lab manual to find the image formed by the converging lens. (e) Label the quantities h, s, h', s' in your ray diagram. (f) Name your complete ray diagram as Fig. 2 which will be a part of your lab report. (g) Measure the values of image position and size (s' & h' ) from your Fig. 2 and record the data in Table 2. (h) Calculate m = h / husing the measured h' and record it in Table 2. (i) From your Fig. 2 to determine the nature of the image. 00 Erect or inverted? . Enlarged or reduced? 20 Record above results in Table 2.
