WebThen using the de Broglie equation we can find the wavelength of the electron at this energy. Electron wavelength (λ) = h/p = hc/E = [6.63x10-34 x 3x108]/9.6x10-10 = 2.1x10-16 m This wavelength is less than the "diameter" of a nucleon and so these very high energy electrons can be used to probe the "structure" of the proton or neutron. WebAs electrons are passed down the chain, they move from a higher to a lower energy level, releasing energy. Some of the energy is used to pump H ^+ + ions, moving them out of the matrix and into the intermembrane space. This pumping establishes an electrochemical gradient.
