For above transitions in hydrogen like atoms, select the incorrect relation(s).

Options

A. `v_3 = v_1 + v_2`
B. `v_3 = (v_1 v_2)/(v_1 + v_2)`
C. `lambda_3 = lambda_1 + lambda_2`
D. `lambda_3 = (lambda_1 lambda_2)/(lambda+ lambda_2)`

Answer

A, D

Explanation

`E_3 = E_1 + E_2 implies hv_3 = hv_1 + hv_2 implies v_3 = v_1 + v_2 `
`c/(lambda_3) =c/(lambda_2) , 1/(lambda_3) , 1/((lambda_1) , 1/((lambda_2) , lambda_3 = (lambda_1 lambda_2)/(lambda_1 + lambda_2)`
