The hydrogen spectrum is an example of line emission spectrum. It is because a definite amount of energy is emitted when electron moves from higher energy state to lower energy state. Johannes Rydberg gave formula which could describe all the series of lines in hydrogen spectrum, ¯ν=109,677(1n2i−1n2f)cm−1Q. The number of spectral lines obtained in H-atom spectrum when electrons de-excites from 4th excited state to ground state is
