Taking the hydrogen atom as an example, when the electron of the hydrogen atom falls to the second energy level (n = 2), the visible light spectrum is produced creating the line spectrum displayed if Fig. 67 × 10 −27 kg. If an electron transitions from a higher orbit to a lower orbit it will emit a photon, since it has to decrease its energy to match the binding energy of the new orbit. Examples of hydrogen atom probability densities. When an electron undergoes a transition to a lower energy level, it emits a photon of a very specific wavelength. 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. For Hydrogen atom, when electron transition from a higher orbit to the orbit n = 2, the corresponding series of spectral lines is.
