At room temperature, most of the atoms of atomic hydrogen contain electrons that are in the excited states. A tube is filled with atomic hydrogen. Electromagnetic radiation with a continuous spectrum of wavelengths, including those in the Lyman, Balmer, and Paschen series, enters one end of this tube and leaves the other end. The exiting radiation is found to contain absorption lines. Do you expect there to be a greater or lesser number of absorption lines in the exiting radiation, compared to the situation when the electrons are in the ground state?
