Fifth spectrum is low pressure sodium, but with secondary lines exaggerated. Sixth spectrum is argon, typical of an argon glow lamp. Oxide lines which may appear in the flame spectrum are not shown. Next spectrum is zinc, drawn using a wavelength table and a photo by Ioannis Galidakis of a zinc arc spectrum. Intensity of the red line is shown for the slightly greenish light blue usual zinc arc, but Ioannis reports getting a pinkish zinc arc and shows the red line to be brighter.
Next spectrum is barium.
Oxide lines are not included. Next spectrum is krypton. Ion lines typical of flashlamp use are not included. Next spectrum is that of the most common variety of metal halide lamp, which is basically a mercury vapor lamp enhanced with iodides of sodium and scandium. An actual typical xenon spectrum generally has a strong continuous spectrum, which I show more dimly than actually occurs in order to show the lines.
