WebApr 14, 2024 · a) The energy of a photon absorbed by a hydrogen atom can be calculated using the formula: E = (hcR)/n^2, where h is Planck's constant, c is the speed of light, R is the Rydberg constant, and n is the principal quantum number of the initial state. 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 ...
