Question

Explain what is hydrogen spectrum?

Answer 1

Hydrogen Spectrum:

1. The hydrogen spectrum is the line spectrum emitted by a hydrogen atom when an excited hydrogen atom returns to its ground state.
2. The various levels of excited state from which a hydrogen atom can return to its lower energy state give rise to various series.
3. These series are the Lyman series, Balmer series, Paschen series, Brackett series, and Pfund series.
4. Rydberg's formula gives the wavelength of the hydrogen spectrum as,

$\frac{1}{\lambda }=R\left(\frac{1}{{n_1}^2}-\frac{1}{{n_2}^2}\right)$

Where, $R$ is the Ryberg's constant,

$n_1$ is the initial energy level and $n_2$ is the final energy level.
