Although colorless or white when pure, anatase in nature is usually a black solid due to impurities. In optics, and by analogy other branches of physics dealing with wave propagation, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency; sometimes the term chromatic dispersion is used for specificity to optics in particular.. A medium having this common property may be termed a dispersive medium (plural dispersive media).
