The energy levels of certain atom are represented in the following figure. During the transition from 2E to E level, a photon of wavelength is emitted. The wavelength of photon produced during transition from 4E 3 level to E will be

Step-by-step solution

The energy of an emitted photon during a transition is given by E = hc . For the transition from 2E to E : E₁ = 2E - E = E E = hc For the transition from 4 3 E to E , let the wavelength be ' : E₂ = 4 3 E - E = E 3 E 3 = hc ' Substituting E = hc into the above equation: 1 3 ( hc ) = hc ' ' = 3 Answer: 3
