| Abstract | Discharge tubes are useful tools for teaching emission spectra and the discrete energy levels of the Bohr model. A new setup uses a plasma globe to illuminate the discharge tube and allows a higher degree of interactivity owing to the omission of a traditional, high-voltage power source. The decreased power consumption also reduces the heating of discharge tubes, which is conducive both to increased interactivity and ease of use. Furthermore, the power source is a relatively inexpensive toy that is widely available. (Contains 2 figures.) (As Provided). |
