The electron in a hydrogen atom jumps back from an excited state to ground state, by emitting a photon of wavelength λ0=1615R, where R is Rydberg's constant. In place of emitting one photon, the electron could come back to ground state by
A
Emitting 3 photons of wavelengths λ1,λ2 and such that 1λ1+1λ2+1λ3=15R16
