Pre-Lab Questions to Lab 1 - Error Analysis

  1. Consider Fig. 3 of the Error Analysis lab description. Suppose that in an experiment you produced a similar plot, except that your calculated error bars were much smaller than those shown on the plot of Fig. 3. Comment on the situation where the best-fit line crossed NONE of the calculated error bars.

  2. Now consider Fig. 4 of the Error Analysis lab description. If the y-intercept represented a quantity of interest in the experiment (i.e., one of the physical quantities that the experiment was designed to measure), comment on the how the experiment should be designed from the point of view of the range of "x-values" over which the individual data points are taken.

  3. Use the Web of Science (a link to this site is located on the PHY293 web page) to locate and download the journal article "Youngs Double-Slit Experiment With Atoms - A Simple Atom Interferometer", O. Carnal and J. Mlynek, Physical Review Letters, 66 (21): 2689-2692, May 27, 1991. Indicate on the article the 5 parts of the "Full Report" format contained in the PHY 293 course syllabus. Turn in the annotated journal article with your written answers to questions 1 & 2 above.
