Question

In hydrogen and hydrogen like species emissiom spectrum is given as

Answer 1

Explanation:

The spectral series of hydrogen, on a logarithmic scale.

The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom. The classification of the series by the Rydberg formula was important in the development of quantum mechanics. The spectral series are important in astronomical spectroscopy for detecting the presence of hydrogen and calculating red shifts.
