Detailed Solution
Series limit means the shortest possible wavelength (maximum photon energy) and first line means the largest possible wavelength (minimum photon energy) in the series.v=C1n2−1m2 (where C is a constant)For series limit of Lyman series:n=1,m=∞ ⇒ v1=CFor first line of Lyman series:n=1,m=2 ⇒ v2=3C/4For series limit of Balmer series:n=2,m=∞ ⇒ v3=C/4Only option (a) is correct.
