The first line in the Lyman series has wavelength λ. The wavelength of the first line in Balmer series is

(a) 29λ              (b) 92λ
(c) 527λ            (d) 275λ

(d) For first line in Lyman series λL1=43R     ..... (i)
For first line in Balmer series λB1=365R          ..... (ii)
From equation (i) and (ii)

λB1λL1=275λB1=275λL1λB1=275λ
