The given figure indicates the energy levels of a certain atom. When the system moves from \(2E\) level to \(E\), a photon of wavelength \(\lambda\) is emitted. The wavelength of photon produced during the transition from level \(\dfrac{4E}{3}\) to level \(E\) is:
1
\(\lambda/ 3\)
2
\(3\lambda/ 4\)
3
\(4\lambda/ 3\)
4
\(3\lambda\)
