EASY
IMPORTANT

In the hydrogen atom Hα line arises due to transition of electron from 3rd orbit to 2nd orbit. In the spectrum of singly ionised helium there is a line having almost the same wavelength as that of line. This is due to transition of electron between the orbits n1 to n2. Value of n1×n2, is _____

MEDIUM
IMPORTANT

The electron in a hydrogen atom jumps back from an excited state to ground state, by emitting a photon of wavelength λ0=1615R, where R is Rydberg's constant. In place of emitting one photon, the electron could come back to ground state by
