A photon of wavelength `lambda` is absorbed by an electron confined to a box of length `sqrt(35hlambda//8mc)`. . As a result, the electron makes a transition from state k = 1 to the state n. Subsequently the electron transits from the state n to the state m by emitting a photon of wavelength `lambda'=1.85lambda`. Then
