2. Copper (Cu) is a metallic conductor with a density of 8.94 g/cm³ and 1 free electron per atom. Assuming that copper can be modelled as a free electron Fermi gas: (a) Derive and calculate the value of the Fermi wavevector and the Fermi energy. [4] (b) Explain what is meant by the plasma frequency wp and calculate its value for copoper. [3] (c) Explain why the value found for wp is inconsistent with the observation that copper metal has a red appearance in colour. Explain why the model used to determine the plasma frequency breaks down. [4]
