... In Bohr’s model , the velocity of the electron is quantized as vn = α c/n, where α = 1/137 is the fine structure constant. Since αc = 2.19 × 106 m/s, we see that only the velocities in (b) and (d) are allowed, being given by the above relation with n = 1 and n = 2 respectively. The quantities in (a) ...
