Purpose:Shows several atomic and molecular line spectra
Description:Use hand-held diffraction gratings to show a number of line spectra. Many of these tubes are rather weak, so this one works best for smaller groups where observers can get close to the light. Sources, which must be inserted and removed as needed by the instructor, include: hydrogen, helium, neon, argon, xenon, mercury vapor, iodine, chlorine, and oxygen (atomic spectra), carbon dioxide, water vapor, and air (molecular spectra).
