Results and Discussion: Fluorescent, incandescent and Helium light spectra were observed using a spectroscope and the USB2000 Spectrometer along with the spectra of various known salts: SrCl 2 , NaCl, LiCl, KCl, and CaCl 2 . An unknown mixture of salts and Hydrogen light was also observed and their wavelength and/or intensity is recorded as follows: Unknown #3
