Answer 2

As we know, n 1 =1No of lines =(n 2 −n 1 +1)(n 2 −n 1 )/2=10n=5.Four lines are observed in the ultraviolet region of the spectrum. These corresponds to the transitions 5→1,4→1,3→1,2→1

As we know, n 1 =1No of lines =(n 2 −n 1 +1)(n 2 −n 1 )/2=10n=5.Four lines are observed in the ultraviolet region of the spectrum. These corresponds to the transitions 5→1,4→1,3→1,2→1So, no of lines in U.V. (Lyman series) spectrum = 4.
