Quantum and atomic physics

  1. Sep 1, 2013 #1
    Hi, Please help me I am lost. I particle in a box model , equation for energy show that the energy increases as n increases, but in Borh's theory n^2 is in the denominator showing that as n increase, the energy decrease, I see the condradiction here. Am I right?

    Why should we apply Bohr's model to a particle in a box? Regardless, note the negative sign in Bohr's equation. As the principal quantum number "n" increases the energy because less negative. So in both cases its getting higher.

    The Bohr energy is increasing even with n2 in denominator, because there is a negative sign. The energy is getting closer to zero from below - thus it is increasing.
