The emission spectrum of hydrogen is found to satisfy the expression for the energy change. teiangle E (in joules) such thatTriangle E= 2.18x10(1/n21 - 1/ n21) J where n1 = 1, 2, 3..... and = n2, 3, 4....... The spectral lines correspond to Paschen series to:
(1) n1= 1 and n2 = 2,3,4,
(2) n1= 3 and n2= 4,5,6,
(3) n1= 1and n2= 3,4,5,
(4) n1= 2 and n2= 3,3,5
(5)n1= 1 and n2 = infinity
Ans: n1= 3 and n2= 4,5,6,
