Question

The given diagram indicates the energy levels of a certain atom. When the system moves from 2E level to E level, a photon of wavelength λ is emitted. The wavelength of the photon emitted during its transition from 4E/3 level to E level is.

Correct answer: D. ΔE(2E→E) = E = h*c/λ. ΔE(4E/3→E) = E/3 = h*c/λ_new. Ratio: E/(E/3) = λ_new/λ => λ_new = 3λ.
