The energies of energy levels A, B and C for a given atom are in the sequence E_A < E_B < E_C. If the radiations of wavelengths \lambda_1, \lambda_2 and \lambda_3 are emitted due to the atomic transitions C to B, B to A and C to A respectively then which of the following relations is correct ?

Correct Answer is : λ3 = λ1λ2λ1+λ2

\lambda_1+\lambda_2+\lambda_3 = 0

\lambda_3 = \lambda_1^2 + \lambda_2

\lambda_3 = \lambda_1 + \lambda_2

\lambda_3 = \frac{\lambda_1\lambda_2}{\lambda_1+\lambda_2}

The energies of energy levels A, B and C for a given atom are in the sequence EA < EB < EC. If the radiations of wavelengths λ1,λ2 and λ3 are emitted due to the atomic transitions C to B, B to A and C to A respectively then which of the following relations is correct ?

λ1+λ2+λ3 = 0
λ3 = λ12+λ2
λ3 = λ1+λ2
λ3 =
λ1λ2
λ1+λ2
