Homework Statement



What are the similarities and differences between the quantization of angular momentum in the Schrodinger theory and in the Bohr model?


Homework Equations



?

The Attempt at a Solution



Similarities:
-In both theories, the principal quantum #, n, determines the energy levels.
-Identical energy levels are determined for Hydrogen.

Differences:
-While the Bohr model was limited to one dimension, Schrodinger's thory accounts for all 3


I feel that these answers are very obvious and that I am missing the more fundamental points of angular momentum. Any insight?

Actually the Bohr model is also 3D. it turns out that the motion of the electron is circular (one parameter = 1DOF), due to angular momentum conservation, because of the central potential.

What's the quantization rule for angular momentum in the Bohr model ? What about wave mechanics of Schrödinger ?
 

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...

Thread 'Help to convert units of a simple formula'

The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
