A collection of H-atoms in 9th excited state returns to ground state . Calculate ratio of total number of spectral lines emitted without emitting any line in Brackett series to number of Brackett series lines .

In a sample of hydrogen atoms, electrons jump from 10^(th) excited state to ground state. If X are the number of different ultraviolet radiations Y are the number of different visible radiations and Z are the possible number of different infrared radiations from 10^(th) excited state to third level. The value Z-(x + y) is (Assuming all the Balmer lines lie with in visible region)
