Set up the equipment (one-lens optical system) as shown in Figure 10. Turn on the light source. L ght Source Crossed Arrow Target Figure 10: Experiment Setup for Optical System with One Lens Place the crossed arrow target (object) close to the light source on the optics bench. Select one of the two lenses provided. Record its focal length, f, in the report le. Place the lens some distance greater than the lens focal length (object distance do). Place the viewing screen some distance from the lens. Slide the viewing screen toward or away from the lens to obtain a sharp (focused) image of the target on the viewing screen. The viewing screen is now at an image distance d,- from the lens. Use the ruler to determine the object size ho, the image size hi (size of the same element of the target you chose for the object) and also the object and image distances, do and 11: (use optical bench ruler in these cases.) Record the measured values in the table. Calculate the image distance d,- using Equation 2 and record its value in the same table. Calculate and record the values of image magnication using Equation 3 and two different sets of data, the one with measured heights, M = $, and the other one with measured object and 0 d. image distances, M = d'. 0 . Draw a ray diagram (with at least two principal rays) on a sheet of paper in appropriate scale (as an example, it can be 1m to 10 cm) for the object like in Fig. 6 placed perpendicular to the optical axis at the distance do from the lens. Scale for the object height can be different from the scale for distances along the optical axis. With a ruler, measure the image distance (scale it back) and record the values of the image distance in the same table. . With the ruler, measure the height of the image in the ray diagram and scale it back. Calculate the magnication of the image. Record those values in the same table. Take a picture of the ray diagram you drew and insert it in your report le. . Move the lens closer to the object and further from the object. Repeat measurements and calculations described in steps 1-4 at least 5 times. Be careful with signs of the image distance and magnication. You do not need to draw the ray diagrams for those measurements. Record the data in your report le. . Place lens 2 with the focal length f2 at some distance d 'om lens 1 with the focal length f1 as 10. ll. 12. l3. 14. 15. shown in Figure 11. Light Source Crossed Arrow Tamer Figure 11: Experiment Setup for Optical System with Two Lenses Within the restrictions of the optics bench length (l m) and the rst length object distance to form a real image, nd where a sharp image is formed after the second lens when intermediate image is between two lenses. Measure do, d, d;', and k; values and record them in your report le. Calculate experimental magnication value for the two-lens system and record it as well. Remove the second lens and place the screen at the distance from the rst lens where a sharp image can be clearly seen. Measure d.- and h.- values and record them in the report le. Calculate experimental magnication value for the rst lens and record it as well. Using do , d, f; and 1'} values calculate d; , do', and d.\" using Equations 4 and 5. Calculate the magnication for each lens as well. Calculate the theoretical value of the magnication of the two-lens system, m = MM '. Don't forget the Sign rules. For two-lens system, nd where a sharp image is formed after the second lens when intermediate image is beyond the second lens. Repeat steps 11 13 for this case. Draw ray diagrams with approximate scale for both cases. You do not need to make any measurements from themStep by Step Solution
