The Balmer series in a hydrogen atom relates the possible electron transitions down to the n = 2 position to the wavelength of the emission that scientists observe.In quantum physics, when electrons transition between different energy levels around the atom (described by the principal quantum number, n ) they either release or absorb a photon. The lines appear in emission when hydrogen atoms' electrons descend to the fourth energy level from a higher level, and they appear in absorption when the electrons ascends from the fourth energy level to higher levels.
