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 wavelength of emitted radiations are `lambda_(1), lambda_(2), lambda_(3)` and `lambda_(4)` respectively. then approximately

Hydrogen H, deuterium D, singlyionized helium He^(+) and doubly ionized lithium L^(++) all have one electron around the nucleus. Consider n=2 and n=1 transition. Thewavelengths ofthe emitted radiations are lamda_(1),lamda_(2),lamda_(3) and lamda_(4) respectively. Then approximately:

Hydrogen (""_(1)H^(1)) , Deuterium (""_(1)H^(2)) , singly ionized Helium (""_(2)He^(4))^(+) and doubly ionized lithium (""_(3)Li^(6))^(++) all have one electron around the nucleus. Consider an electron transition from n = 2 to n = 1. If the wavelength of emitted radiation are lambda_(1),lambda_(2),lambda_(3) and lambda_(4) respectively then approximately which one of the following is correct?

Hydrogen ("_1^1H) deuterium ("_1^2H) , singly ionised helium ("_2^4H)^+ and doubly ionised lithium ("_3^6Li)^(++) all have one electron around the nucleus. Consider an electron transition from n=2 to n=1 . If the wavelengths emitted radiation are lambda_1,lambda_2,lambda_3 and lambda_4 respectively then approximately which one of the following is correct?
