Identify the value ofninitial (initial) forthe transition giving rise to this emission Identify the value ofnfinal (final) for thetransition giving rise to this emission
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.
