Transition between three energy energy ...

Transition between three energy energy levels in a particular atom give rise to three Spectral line of wevelength , in increasing magnitudes. `lambda_(1), lambda_(2)` and `lambda_(3)`. Which one of the following equations correctly ralates `lambda_(1), lambda_(2)` and `lambda_(3)`?

A

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

B

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

C

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