Question

Energy levels A, B and C of a certain atom correspond to increasing values of energy, i.e. $E_{A} <$ $E_{B} < E_{C}$ . If $λ_{1}, λ_{2}, λ_{3}$ are the wavelengths of radiation corresponding to the transitions $C \to B, B \to A$ and C → A respectively, then:

Options:

Answer:

B

Solution:

$E_{CB} + E_{B A} = E_{C A} \Rightarrow \frac{1}{λ _{1}} + \frac{1}{λ _{2}} = \frac{1}{λ _{3}}$ .
