WebBohr’s expression for the quantized energies is: En = − k n2 with n=1,2,3, ... In this expression, k is a constant comprising fundamental constants such as the electron mass and charge and Planck’s constant. Inserting the expression for the orbit energies into the equation for ΔE gives WebBohr guessed that angular momentum might be quantized, and then he calculated the consequences of that in order to see if they matched up with experimental observations. His guess did a pretty good job of explaining the emission spectrum of hydrogen atoms. ( 7 votes) Adam Rahimov 6 years ago how Bohr came up with L=n*h/2*pi.
Web10 oct. 2014 · Use the Bohr quantization rules to calculate the energy levels for a particle moving in a potential where k is positive and very large. Sketch the form of the potential (done) and show that the energy values approach $E_n = kn^2$, where k is a constant.
