SUMMARY

The discussion focuses on calculating energy levels and transition frequencies in Bohr's model of the hydrogen atom. The key equations utilized include the quantization of angular momentum (L=ħn) and the transition frequency formula (ν=(Ei-Ef)/h). The user successfully derived the energy levels as En=-13.6/n², confirming that the results align with classical physics in the limit of high quantum numbers, adhering to the correspondence principle. The inquiry centers on whether all assumptions were adequately applied in the calculations.

PREREQUISITES
  • Understanding of Bohr's model of the hydrogen atom
  • Familiarity with quantum mechanics concepts such as quantization of angular momentum
  • Knowledge of electromagnetic radiation and its relationship to energy transitions

  • Investigate the application of transition frequencies in spectroscopy
USEFUL FOR

Students of physics, particularly those studying quantum mechanics and atomic theory, as well as educators seeking to clarify Bohr's model and its applications in real-world scenarios.

Homework Statement


In Bohr's model the allowed paths are those which the angular momentum is quantized by L=ħn and the electromagnetic radiation emission is only by transition through two of them
ν=(Ei-Ef)/h. I am asked to use the above assumptions to calculate the energy levels and the frequencies of transitions in a single electron atom. I am then asked to show that in the limit of high quantum numbers the result reduces to the classical one (the correspondence principle).

Homework Equations

The Attempt at a Solution


I managed to arrive at the expected expression for the energy levels, however I am not sure I explicitly used all the assumptions as instructed. What I did was this:
V=-e2/r, |F|=-∇V=e2/r2=mv2/r, hence v2=e2/mr=(nħ/mr)2
En=1/2*mv2-e2/r=-e2/2rn where rn=n2ħ2/me2=-13.6/n2
Does this suffice? Does this after all meet the instructions?
