Energy levels {\A}, {\B} and {\C} of a certain atom corresponding to increasing values of energy i.e., E_A< E_B< E_C. If \lambda_1, \lambda_2 & \lambda_3 are the wavelengths of a photon corresponding to the transitions shown, then [AP EAPCET 23 May 2024 S1]

Correct Answer is : λ3=λ1λ2(λ1+λ2)

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

\lambda_3^2=\lambda_1^2+\lambda_2^2

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