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". Four of these are the spectra of elements, while the other two are those of a fluorescent light and an incandescent light bulb. The four elements are Hydrogen, Helium, Sodium, and Mercury, in order of their atomic masses. Using the emission-line wavelengths given in Reference Table 19.1, identify the spectra for He, Na, and Hg, and H. You must ignore spurious lines outside of the visible-light region ("visible light" is roughly defined as the wavelengths between 380 nm to 790 nm), and be aware that some lines listed in the tables are very faint. Another useful hint is that fluorescent lights contain significant traces of a certain heavy-metal impurity. From the spectra, identify the corresponding elements.
