Ending Frequency

Postby Zane Mills 1E » Fri Oct 20, 2017 8:57 pm

When calculating the frequency of a wavelength from a given energy (emitted electron eqn) do you used the total energy given at the end of the equation or do you strictly use the kinetic energy because that is the actual energy once the photon leaves?

Can you elaborate on your question ? Emitted electron equation doesn't usually give energy.

I am not sure if I understood your question correctly, so feel free to give feedback and elaborate. Which light are you trying to calculate the frequency for? If it's the incoming light that hits the electron, then you use the given total energy of that incoming light or the energy that you calculated for it. You would not use the kinetic energy. Please correct me if I am wrong.

If you are talking about the Bohr frequency model (just because it includes E and results in frequency) then you are going to use the delta E/change in energy
