One series of emission lines for the hydrogen atom, 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. The lowest energy line in this series occurs for an electron falling fromn= 6 to n = 5. AE = -2.662x10-20 J 1 = 7.462x106 m v = 4.018x1013 1/s (Hz)

9. One series of emission lines for the hydrogen atom, 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.

The lowest energy line in this series occurs for an electron falling from n = 6 ton=5.
AE = -2.662x10-20 J
2 = 7.462x10-6 m
v = 4.018x103 1/s (Hz)
