WebA photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by. E = hf = hc λ (energy of a photon), 29.12. where E is the energy of a single photon and c is the speed of light. When working with small systems, energy in eV is often useful. WebThe energy of the emitted photon is given by the Rydberg Formula. This formula is essentially the subtraction of two energy levels. It is: where n1 < n2 and (as before) E0 = 13.6 eV. With the restriction n1 < n2 the energy of the photon is always positive. This means that the photon is emitted and that interpretation was the original ...
