Spectrum of the hydrogen atom

If the electron goes from the state Ek to En, when k>n, a quantum of radiation is emitted with an energy equal to the energy difference of these levels.

$E={\frac {m_{e}\cdot e^{4}}{8\cdot \epsilon _{0}^{2}\cdot h^{2}}}\cdot \left({\frac {1}{n^{2}}}-{\frac {1}{k^{2}}}\right)$

The frequency of the radiation is given by the formula E=hf Due to the quantization of energy, the radiation is discontinuous and forms a so-called series of lines.

The Lyman series lies in the ultraviolet part of the spectrum and corresponds to the transition of electrons to the basic energy level n=1.

The Balmer series is a transition to n=2 and is in the visible part of the spectrum. Other series (n=3, etc.) are in the infrared part of the spectrum.
