Bohr Frequency Condition

Postby timothy_ho_4B » Tue Oct 23, 2018 2:10 am

I understand that in the equation E = - h R / n^2, E is symbolizing the change in energy, but would using the E from E = hv be equal to that change in energy? and what does the n stand for in that equation? The initial or final energy level?

E in that equation actually equals the energy of an electron in that energy shell, not the change in the energy. But yes, you can connect the E=-hR/n^2 to the E=hv equation.

En is actually the energy of an electron in a energy level which is denoted by n. If it is a problem dealing with atomic spectra and the Rydberg Equation, such as asking to find the frequency of a proton that was emitted as it transitioned from the 5th or 3rd energy level, then you have 2 n and therefore, one n is the final energy level and other is the is the initial energy level.
