You are given the following three pairs of image and corresponding object distances (1.01 mm, 100.030m), (10.02 mm, 1,000.020 m), and (99.97 mm, 10,000.025 m). Assuming that the standard deviations of the image and object distance measurements are ±20 µm and ±20 mm, respectively, what are the corresponding image scale and standard deviation using each of these pairs? What would you infer from these derived scales/standard deviations?
