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

A

`lambda_(1)=2lambda_(2)=3lambda_(3)=4lambda_(4)`

B

`4lambda_(1)=2lambda_(2)=2lambda_(3)=lambda_(4)`
