We then observed the wavelength lines for the hydrogen lamp. Again turning the dial counter-clockwise, we saw the following four lines:

LINE Violet Blue Blue-Green Red
Raw Data 1 (nm) 410-411 434-435 486-487 659-660
Raw Data 2 (nm) 410-411 434-435 486-487 659-660
Raw Data 3 (nm) 410-411 434-435 486-487 659-660
  • I also observed a bright region in the yellow part of the spectrum, however, it did not focus itself on a specific wavelength.

The hydrogen lamp was quite hot after I turned the lamp off.

  • I would expect a similar spectrum for deuterium as for regular hydrogen.

We then observed the following emmision spectrum for the deuterium lamp:

LINE Violet Blue Blue-Green Red
Raw Data 1 (nm) 410-411 434-435 486-487 659-660
Raw Data 2 (nm) 410-411 434-435 486-487 659-660
Raw Data 3 (nm) 410-411 434-435 486-487 659-660
  • I observed a similar yellow region in the deuterium lamp of no specific wavelength.

Two astonishing things occurred:

  1. The hydrogen and deuterium lamps have almost the same spectrum.
  2. Both the hydrogen and deuterium lamps have the same spectrum on every measurement.
