Frequency and de Broglie Equation Derivation

Postby Victoria Li 1L » Fri Oct 11, 2019 12:05 pm

During lecture today, it was mentioned that the frequency (from the E=hv equation) can't be calculated for de Broglie wavelengths since those are for electromagnetic radiation, not electrons. However, the de Broglie equation was derived from E=hv so I was wondering, do the electrons have a frequency or not?

The equations used to derive the De Broglie wavelength equation cannot be used for electrons. Lavelle just demonstrated the way that the equation was originally derived so that we would understand where the equation comes from.

No, electrons has a frequency of zero, Lavelle just demonstrated the different forms of the equation, since in some chemistry problems we will have to use the de Broglie equation.

Surely, the equation is derived from the equation but you have to also consider that because electron is not electromagnetic radiation, (it has wavelike movement and all but it isn't the radiation) you cannot apply those equations to De Broglie's equations.
