2 Atomic Spectra Laboratory Worksheet Page 2 of 5 Part B: Hydrogen Spectrum Colour λ (10 7 m) n θ 1 θ 2 Violet Blue Blue-Green Red Data Table 2 Analysis B-1: For each spectral line, calculate (1) the diffraction angle θ; (2) the wavelength λ; and (3) the percentage discrepancy to compare your experimental value for wavelength with the accepted value. Show a sample calculation and be sure to attach a copy of the spreadsheet to your laboratory report. Question B-1: Comment on the accuracy of your experimental values for the wavelengths of hydrogen compared to the known values. Analysis B-2: perform a suitable linear least squares fit to your data: wavelength λ exp and n so that the Rydberg constant R H can be determined. Plot a suitable linear graph for your data. Also show on the graph the straight line that was obtained by the linear least fit to the data as well as the error-bar of your data. Be sure to attach a copy of the graph (with the spreadsheet) to your laboratory report.
