3. In an FCC lattice, the dispersion relation of phonons may be taken to be identical to the 1-D model, with equilibrium separation a being equal to the distance between close packed nearest neighbours. Calculate the force constant of gold. Given atomic weight = 197 g mol−1, and density = 1.93 × 10^4 kg m^−3. The speed of sound in gold = 3.24 × 10^3 m s^−1.
