Procedure: A spectrometer was used to observe and record the wavelengths and corresponding colors of emission spectrum from fluorescent light, an incandescent light bulb, a glass tube filled with helium, and a discharge tube filled with hydrogen. A cotton swab with a small amount of each salt solution was burned in the flame of a Bunsen burner and the emission spectra observed. Two salts were mixed and this was repeated in order to see the effects on the resulting spectra and then the unknown salt was observed under the same procedure. Observations: The color of fluorescent light was white, incandescent was yellow-white, helium was white, and hydrogen was a bright pinkish-purple color. The color of the flame
