![]() Instead of allowing for continuous values for the angular momentum, energy, and orbit radius, Bohr assumed that only discrete values for these could occur (actually, quantizing any one of these would imply that the other two are also quantized). The absolute value of the energy difference is used, since frequencies and wavelengths are always positive. In this equation, h is Planck’s constant and E i and E f are the initial and final orbital energies, respectively.
