20. Arc Tubes

Arc tubes of hydrogen, helium, argon, mercury, and a few others can be viewed three-at-a-time with a large holographic grating. Also available is an incandescent light which can be used to look at a continuous spectrum.

Another option is that students can use individual gratings to see spectral lines of these tubes.
