Problem 3: Ray tracing for concave mirrors A 3 cm high object is located 72 cm from a concave mirror with a focal length of 20 cm. For most of the problem however you will be making measurements on the scaled down version shown in the picture. A. Draw a ray diagram to find the image. You only need to draw 2 of the special rays, but you can draw more if you'd like. Use a straightedge and be as accurate as possible. Make sure your rays show the height and orientation of the image. B. Use a ruler to measure the height and location of the object and of your image in the figure, use the appropriate sign to indicate whether the image is real or virtual. C. Calculate the ratio of the measured height of the image to that of the object. Repeat the calculation for the measured locations. Compare both ratios. D. Using the ratios in part C and the given values in the problem, where would you expect the image to be located? What do you expect its height to be? E. Use the mirror formula to calculate the location of the object. Use the equation(s) for the magnification to calculate the magnification and the height of the image
