Question

Excited H atoms have many emission lines. One series of lines, called the Pfund series, occurs in the infrared region. It results when an electron changes from higher energy levels to a level with $n=5 .$ Calculate the wavelength and frequency of the lowest energy line of this series.

Step 1

097 \times 10^7 \, m^{-1} \) is the Rydberg constant, $ n_f = 5 $ is the final energy level, and $ n_i = 6 $ is the initial energy level. \[ \Delta E = - (1.097 \times 10^7) \left( \frac{1}{5^2} - \frac{1}{6^2} \right) \] \[ \Delta E = -2.663 \times 10^{-20} Show more…
