Answer

  1. The transition of electrons between two energy levels.
Explanation:
The observed spectral lines are caused by the transition of electrons between two energy levels in an atom.
The emission spectrum of the hydrogen atom is divided into many spectral series, with wavelengths that are given by Rydberg’s formula.
