Sep 01, 2017 · Electron Wavelength. We can calculate the de Broglie wavelength of an electron from the potential difference, V, that accelerated it. Change in electric potential energy gained = eV. This is equal to the kinetic energy of the electron The velocity is therefore given by: We can substitute this into to get: Sand Analogy
