Equipment:
1 hydrogen spectrum tube 1 transformer 2 1meter sticks 1 2meter stick1 ring stand 1 testtube clamp 1 cclamp 1 diffraction grating 2 white index cards

grating statistics: 13400 lines per inch = 1.90 x 10^{6} meters/slit


Complete the following data table:
distance (meters) from grating to 100 cm (10.00 dm) mark on meter stick ________ 


Refer to the following information for the next six questions.
After all of the data has been collected, and your preliminary calculations have been signed off by Mrs. Colwell, use the spreadsheet 1spectrum.xls (in your period folder) to determine your experimental wavelengths and percent errors of the red, cyan, and violet lines in the Balmer's series of the hydrogen spectrum. Immediately after opening the EXCEL file, resave it as LastnameLastnameLastnameSpectrum.xls. You are to only input values into the yellow cells  the blue cells have already been programmed for you. If your errors are large, see Mrs. Colwell about recollecting your data. Once you are satisfied with your results, type in the names of your group members and save your spreadsheet a final time. A printout of your file is required as part of your lab report.
