Question
The ratio of the wavelengths of the longest wavelength lines in the Lyman and Balmer series of hydrogen spectrum is :
Options
A.
B.
C.
D.
Solution
for maximum λ = 
(n1 = 2 → n2 = 1 Lymen
(n1 = 3 → n2 = 2 Balmer
Longest λLymen =
Longest λBalmer =
(n1 = 2 → n2 = 1 Lymen
(n1 = 3 → n2 = 2 Balmer
Longest λLymen =
Longest λBalmer =
