For a certain atom, there are energy levels A,B,C corresponds to energy values `E_(A)ltE_(B)ltE_(C)`. Choose the correct option if `lambda_(1),lambda_(2),lambda_(3) `are the wavelength of rediations corresponding to the transition from C to B,B to A and C to A respectively.

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
`(1)/(lambda_3)=(1)/(lambda_1)+(1)/(lambda_2) rArr lambda_(3) =?`
