The wavelength of a spectral ine for an electronic transition is inversly related to:(1) No, of electrons undergoing transition(2) The nuclear charge of the atom(3) The velocity of an electron undergoing transition(4) The difference in the energy levels involved in the transition

Answer»

We know,

∆E=hc/λ

So,

λ~1∆E

Hence, the wavelength of spectral line for an electronic transition is inversely related to the difference in the energy levels involved in the transition.
