The Fermi velocity vF is defined by  where EF is the Fermi energy. The Fermi energy for silver is 5.5 eV. (a) Calculate the Fermi velocity, (b) What would be the wavelength of an electron with this velocity? (c) How does this compare with the lattice spacing of 0.41 nm? Docs the order of magnitude make sense?
