SUMMARY
The Fermi energy of copper is established at 7 eV. The Fermi momentum of an electron in copper can be calculated using the formula p_F = sqrt(2 * m * E_F), where m is the electron mass and E_F is the Fermi energy. The de Broglie wavelength of the electron is determined using the equation λ = h / p_F, where h is Planck's constant. The Fermi velocity can be derived from the relationship v_F = p_F / m.
