What is a dispersive medium?
(N/A) dispersive medium is a medium in which the phase velocity of a wave depends on its frequency. In the context of optics,a dispersive medium is one where the refractive index $n$ varies with the wavelength $\lambda$ of light. As a result,different colors (wavelengths) of light travel at different speeds through the medium,causing them to refract at different angles. $A$ classic example of a dispersive medium is glass or water,which causes white light to split into its constituent colors (dispersion) when passing through a prism.
