Solve this: Q.12. Let F 1 be the frequency of second line of Lyman series and F 2 be the frequency of first line of Balmer series then frequency of first line of Lyman series is given by (1) F 1 - F 2 (2) F 1 + F 2 (3) F 2 - F 1 (4) F 1 F 2 F 1 + F 2 Share with your friends Share 9 Shobhit Mittal answered this second line of lyman series.E=13.611-132F1=Ehfirst line of balmer seiresE'=13.6122-132F2=E'hfirst line of thelyman series.E''=13.611-122F3=E''hE''=E-E'=13.611-132-13.6122-132=13.611-122hece F1-F2=F3Regards 9 View Full Answer
