c. The lines in the emission spectrum of hydrogen are assigned to various series.
The Brackett series involves n→ 4 transitions where n =5, 6, 7,… to ∞
Use RH = 2.18 x 10-18 J in your calculations
Determine the full wavenumber range of possible transitions in this series using
calculations for two suitably chosen emissions. Report the emission line
positions in cm-1
.
