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 approximatelyA. `lambda_(1)=lambda_(2)=4 lambda_(3)=9 lambda_(4)`B. `4lambda_(1)=2lambda_(2)=2lambda_(3)=lambda_(4)`C. `lambda_(1)=2lambda_(2)=2sqrt(2)lambda_(3)=3sqrt(2)lambda_(4)`D. `lambda_(1)=lambda_(2)=2lambda_(3)=3sqrt(2)lambda_(4)` |

Answer» Correct Answer - A `(1)/(lamda) prop Z^(2) implies lamda prop (1)/(Z^(2))` `lamda_(1) : lamda_(2) : lamda_(3) :lamda_(4)=(1)/(1^(2)) :(1)/(1^(2)) :(1)/(2^(2)) : (1)/(3^(2))=1: 1:(1)/(4):(1)/(9)` `lamda_(1)=lamda_(2)=4 lamda_(3)=9lamda_(4)` |
