are very likely to observe more lines than what you expect from a pure hydrogen gas emission spectrum. Additionally, hydrogen, being the smallest atom, can also leak out the gas tube, weakening the signal. You should look for the expected lines and ignore the lines from contaminants. Element: Hydrogen Color Measured Wavelength (nm) Expected Wavelength (nm) Matching? (Approximately) There are several additional elemental gas tubes set around the room for you to observe. Choose two. Use your handheld spectrometer and...
