Atoms are 1-dimensionally aligned with an inter atomic distance of 10nm. Let’s assume that the positive charge of the nucleus of the atom is infinitely large so that electrons are confined to a specific atom. Then, what wavelength photons are required to excite electrons from the ground state (n=1) to the second excited state (n=3)?
