The following diagram indicates the energy levels of a certain atom when the system moves from \( 4 E \) level to \( E \). A photon of wavelength \( \lambda_{1} \) is emitted. The wavelength of photon produced during its transition from \( \frac{7}{3} E \) level to \( E \) is \( \lambda_{2} \). The ratio \( \frac{\lambda_{1}}{\lambda_{2}} \) will be
(A) \( \frac{9}{4} \)
(B) \( \frac{4}{9} \)
(C) \( \frac{3}{2} \)
(D) \( \frac{7}{3} \)
