Physics Laboratory Report PHY 151 M0 ERROR ANALYSIS Student Name: Seongeun Jin(36204069) Partner’s Name: Kwon Chon, Date: 22th Jan. 2010 TA name: Zhenzhong Shi -1. Tabulate the values for I recorded in section 1. # i(mm) 1 563 2 569 3 560 4 550 5 559 6 546 7 552 8 568 -2. Determine the average value i of the image-lens distance and its standard deviation σi By using Excel Average 558.375 Standard deviation 8.399617 Average value i of the image-lens = 558mm Standard deviation = 8 mm -3. Use equation 5 to calculate the focal length f of the lens. Eqs.5 f = + oio i = × + 558 170558 170 = 130 mm -4. The partial uncertainty σof is given by the equation: = + = + × . = ± . σof io i 2σo 558170 558 2 3 00 1 76 mm The partial uncertainty σif is given by the equation: = + = + × . = ± . σif io i 2σio 170170 558 2 8 30 0 45 mm Measurement has been made 3mm for σo -5. The net uncertainty σf in the value of f is given by the equation: = + = . + . = . σf σof2 σif2
