Formula and explanation

Formula: L = m e v r = n, where n = 1,2,3,..., = h/(2π). Applicable Conditions: Circular orbits in the Bohr hydrogen atom model. Explanation: This is Bohr's postulate that the orbital angular momentum L of the electron can only be an integer multiple of the reduced Planck constant. This is key to the Bohr model's success in explaining the hydrogen spectrum.
