PHY-257 MP4 Manual Addendum V Procedure V-1: Proceed as directed in the manual with the exception of the value for D. Your target will be taped to the wall at the end of your table, and D will simply be the length of the table. V-2 through V-4: No change from the manual. VI For the report Estimating the uncertainties in this lab is somewhat subjective and non-precise given the nature of the data. VI-1: Calculate the magnification, |m|, of the astronomical telescope using equation 4. Compare it with the experimental value measured in step V-1. Estimate the uncertainty in your measurement by estimating the range of possible values for the numbers of lines visible when calculating m. VI-2: Calculate the magnification, |m|, of the terrestrial telescope using equation 4. Compare it with the experimental value measured in step V-2. Estimate the uncertainty in your measurement

Using Excel, plot 1/i vs 1/o. From the LINEST function, determine the intercept and the uncertainty in the intercept. Now determine the focal length (and its uncertainty) of the lens combination and report this in the form f f σ ± . Calculate the expected value (eqt. 8) and compare it to the experimental value. Does the expected value fall into the range determined by f f ± ? VI-4: Use equation 9 to calculate the expected value for magnification, |m|, for the data taken in step V-4. Compare the calculated and experimental values. Estimate the uncertainty in your measured values. VII Questions No change from the manual....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
