... Intra-band transitions correspond to free electron effects of the Drude model. The sharp absorption lines from atoms (i.e. single resonance frequencies) give way to broad bands and hence absorption bands and not absorption frequencies. The plasma frequency corresponds to the edge where the reflectan ...
