Hydrogen (H), deuterium (D), singly ionized helium (He+) and doubly ionized lithium (Li++) all have one electron around the nucleus. Consider n = 2 to n = 1 transition. The wavelengths of emitted radiations are λ1,λ2,λ3 and λ4 respectively. Then approximately :

λ1=λ2=4λ3=9λ4
4λ1=2λ2=2λ3=λ4
λ1=2λ2=2√2λ3=3√2λ4
λ1=λ2=2λ3=3√2λ4
