For each intercept, calculate a value of f and record it in Table 12.2. 4. Find the percent difference between these two values of fand record them in Table 12.2. Average these two values of f. Find the percent difference between this average and the focal length that you found in Part I. Record these data in Table 12.2. Table 12.2: Focal Length Result from x-intercept Result from y-intercept % difference between results from intercepts Average of results from intercepts Result from Part I % difference between Average of results from intercepts and result from Part I Analysis Part B: Magnification 1. For the first two data points only (the first two lines of Table 12.2), use the image and object distances to calculate the magnification, M, at each position of the lens. Record the results in Table 12.3. (eq. 12.2) M = -a) 35 PASCO
