Analysis Part A: Focal Length 1. Calculate Ild, and 1/d, for all six rows in Table 13.1. 2. Plot 1/dversus 1/d, and find the best-fit line (linear fit). This will give a straight line with the x- and y-intercepts equal to 1/. Record the intercepts (including units) here: y-intercept = 1/- X-intercept -1/- Note: You can play the data and find the best-fit kine on paper or on a computer. 3. For each intercept, calculate a value off and record it in Table 13.2. 4. Find the percent difference between these two values off and record them in Table 13.2. 5. Average these two values off. Find the percent difference between this average and the focal length that you found in Part I. Record these data in Table 13.2. Table 13.2: Focal Length s Result from x-intercept Result from y-intercept % difference between results from intercepts Average of results from intercepts Result from Part 1 % difference between Average of results from intercepts and result from Part 1
