What are waveslength of `Li^(+2)` transition from 3rd orbit to 1st orbit .

An electron in an atom jumping from 3rd orbit to 2nd orbit emits radiation of wavelength lambda_(1) and when it jumps from 2nd orbit to 1st orbit emits radiation of wavelength lambda_(2) . The wavelength of radiation emitted when it jumps from 3rd orbit to 1st orbit is

When the elecrton in the hydrogen atom jupms from 2nd orbit to 1st orbit, the wavelength of radiation emitted is lambda . When the electrons jupms from 3rd orbit to 1st orbit, the wavelength of emitted radiation would be

An electron in the hydrogen atom absorbs energy and jumps to the 4th orbit. It jumps back to the ground state in steps e.g., from 4th to 3rd orbit, then from 3rd to 2nd orbit and finally to the ground state etc. If lambda_(1) is the wave length of line for jump of the electron from 4th to 3rd orbit and lambda_(2) that of the line for jump from 3rd to 2nd orbit, then wavelength of the line for jump from 4th orbit to 2nd orbit would be

The electron in the hydrogen atom undergoes transition from higher orbitals to orbital of radius 211.6 pm. This transition is associated with:

An electron in the hydrogen atom absorbs energy and jumps to the 4th orbit. It jumps back to the ground state in steps e.g., from 4th to 3rd orbit, then from 3rd to 2nd orbit and finally to the ground state etc. If a_(0) represents Bohr radius, the de-Broglie wavelength of the electron when it moves in the 3rd orbit after absorbing same definite amount of energy will be
