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?

We hope that there will be a smaller number of lines for missing almost the entire series of Lyman

Explanation:

The lines of the hydrogen spectrum are well explained by the Bohr model, in this case the lyman series occur when electrons are emitted starting from the n = 1 level, as in this case they indicate that the atoms are in excited state there is no electron available in the base state n = 1, so the emission lines of this series that is in the ultra violet are not present in the radiation.

The other two Balmer series that are in the visible part of the n = 2 level and the Paschen series in the infrared part of the n = 3 level that has electrons for the transition.

In summary: We hope that there will be a smaller number of lines for missing almost the entire series of Lyman

the answer would be c. motion and direction

i hope this : )
