1.	The Balm er series in the hydrogen sp ectru m corresponds to the transition from n_(1) = 2 to n_(2) = 3, 4,........This series lies in th e visible region. Calculate the wave num ber of line associated with the tran sitio n in Balm er series w hen the electron m oves to n = 4 orbit. (R_(H) = 109677 cm^(-1) )
Answer» Solution :`barv=109677 [(1)/(n_(i)^(2))-(1)/(n_(f)^(2))]cm^(-1)` so `n_(i) =2 to n_(f) =4` TRANSITION in BALMER series `=109677 (1/4-1/16)cm^(-1) =20564.44 cm^(-1)`
