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

Options

A. `lambda_3 = lambda_1 + lambda_2`
B. `lambda= (lambda_1 lambda_2)/(lambda_1 + lambda_2)`
C. `lambda_1 + lambda_2 + lambda_3 = 0`
D. `lambda_(3)^(2) = lambda_(1)^(2) + lambda_(2)^(2)`

Answer

B

Explanation

`E = (hc)/(lambda)`
