Energy levels A, B, C of a certain atom ...

Energy levels `A, B, C` of a certain atom corresponding to increasing values of energy i.e., `E_(A) lt E_(B) lt E_(C)`. If `lambda_(1), lambda_(2), lambda_(3)` are the wavelengths of radiations correspnding to the transitions `C` to `B, B` to `A` and `C` to `A` respectively, which of the following statements is correct?

A

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

B

`lambda_(1)+lambda_(2)+lambda_(3) = 0`

C

`lambda_(3)^(2) = lambda_(1)^(2)+lambda_(2)^(2)`

D

`lambda =(lambda_(1)lambda_(2))/(lambda_(1)+lambda_(2))`
