See the Spectrum below. Computer-generated spectra obtained using a spectrophotometer are presented on the pages following the Report Questions. This collection contains six spectra. labeled \"A" through \"F". F our of these are the spectra of elements. while the other two are those oia uorescent light and an incandescent light bulb. The four etements are Hydrogen. Helium. Sodium. and Mercury. in order of their atomic masses. Using the emissionline wavelengths given in Reference Table 19.1. identifyr the spectra for He. Na. and Hg. and H. You must ignore spurious lines outside of the visible-light region (\"visible light\" is roughlv dened as the wavelengths between 38C! 11m to T9121 11m}. and be aware that some lines listed in the tables are veryr faint. Another useful hint is that uorescent lights contain significant traces ofa certain heavv-metal impurity. From the spectra. identify the corresponding elements.
