An electron in an atom jumping from 3rd orbit to 2nd orbit emits radiation of wavelength `lambda_(1)` and when it jumps from 2nd orbit to 1st orbit emits radiation of wavelength `lambda_(2)`. The wavelength of radiation emitted when it jumps from 3rd orbit to 1st orbit is

A

`sqrt(lambda_(1)lambda_(2))`

B

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

C

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