Question

Paschen series are produced when electron from the outer orbit falls into

Answer 1

Answer:

Whenever an electron in a hydrogen atom jumps from higher energy level to the lower energy level to the lower energy level, the difference in energies of the two levels is emitted as a radiation of particular wavelength. It is called a spectral line. As the wavelength of the spectral line depends upon the two orbits (energy levels) between which the transition of electron takes place, various spectral lines are obtained. The different wavelengths constitute spectral series which are the characteristic of the atoms emitting them. The following are the spectral series of hydrogen atom :

Paschen series : This series consists of all wavelength which are emitted when the electron jumps from 'outermost orbits to the third orbit'.

This series is in the infrared region...
