Explanation / Answer

We Know that:     According to Bohr's Atomic model :          1 / = RH ( 1 /ni2 - 1 /nf2 )       1 / 656.7 x10-9 m   = 10 973 731.6m-1 ( 1 / ni2 - 1 / nf2 )        ( 1 /ni2 - 1 /nf2 ) =   1 / 7.2          From theobservation of the values of n        n i = 3         nf = 2          As theprocess is a emission the electron is de-excited from the higherenergy level to lower energy level.
