H-atom is exposed to electromagnetic radiation of `lambda=1025.6` Å and excited atom gives out induced radiation. What is the minimum wavelength of the induced radiation?

A hydrogen like ion He^(o+) (Z = 2) is exposed to electromagnetic waves of 256.4 Å The excited electron gives out induced radiation .Find the wavelength of the induced radiation when the electron de-excites back to the ground state (R = 109677 cm^(-1))

A hydrogen -like ion He^(o+) (Z = 2) is expased to electromagnetic waves of 256.4 Å The excited electron gives out induced radiation .Find the wavelength of the induced radiation when the electron de-excetes back to the ground state (R = 109677 cm^(-1))

Electromagnetic radiation with minimum wavelength is

The IP_(1) of H is 13.6 eV it is expoxed to electromagnetic waves of 1028A^@ and gives out induced radiation .Find the wavelength of these induced radiation

H-atoms is exposed to electromagnetic radition of 1028Å and gives out induced raditions ( raditions emitted wher e^(-) return to ground state ) .Calculate lambda of induced radiations.

The ionisation potential of H-atom is 13.6eV . It is exposed to electromagnetic radiation of wavelength 1028A^(@) and gives out induced radiations, then
