Question

Any attenuating medium must exhibit this phenomenon to preserve causality. The effective mass is proportional to the curvature of curves depicting this phenomenon for quasiparticles, which correspond to the bands in band diagrams. The real part of the dielectric function sharply decreases near strong absorption bands in the “anomalous” form of this phenomenon. (15[1])A “modal” form of this phenomenon spreads out signals in time in multimode (*) optical fibers. (-5[2])Curves of omega as a function of k are called (10[1])this phenomenon’s (10[1])namesake “relations.” (10[2])The phase velocity for a wave is (10[1])non-constant in this phenomenon, causing (-5[1])different frequencies (10[1])to travel at different (-5[1])speeds. (10[1])For 10 points, name (-5[1])this phenomenon in which a wave’s refractive index depends (-5[1])on frequency, exemplified by prisms splitting white light (10[1])into a rainbow.
