When a photon with exactly the right wavelength encounters an atom of the cool gas, it is absorbed and its energy used to kick an electron into a higher orbit; if enough atoms of gas are present, all the photons of that wavelengths are absorbed, while photons with other wavelengths get through. If the electron moves from one energy level to a lower energy level, and if it has enough spin energy to begin with, it will emit a photon equivalent in energy to the difference in the two energy level locations. True For hydrogen, what is the wavelength (nm) of the photon emitted when an electron drops from a 4d orbital to a 3p orbital in a hydrogen atom?.
