If the energy difference between the orbits when an electron in H atom excited to higher energy orbit from its ground state is 12.1eV// atom , calcualte the frequency of radiation emitted (1 eV =1.602xx10^(-19J)) when electron comes back to second energy level.

Answer»

Solution :(i) RELATION between energy and n
(ii) CALCULATION of `n_2` value from the difference in energy.
(iii) calculation of FREQUECNY from energy
(iv) calculation of energy difference BASED on n values
(V) calcualtion of frequency
(vi) `v=0.456xx10^(15)s^(-1)`
