Consider the refractive index of free electrons in copper, at frequencies around the plasma frequency, ωp in the Drude model. Write expressions for the reflectivity R at normal incidence as a function of frequency in the vicinity of ωp. For copper the free electron relaxation time is 1.9 x10-14 s and the plasma energy is 7.8 eV.

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
