SUMMARY
The speed of light in a refractive material is described by the equation c/n, where c is the speed of light in a vacuum and n is the refractive index of the material. The reduction in speed is not due to a change in the fundamental speed of light but rather the result of "Dielectric Dispersion." This phenomenon occurs when atoms in the material absorb and then re-emit the light wave, causing a net delay that manifests as a slower wave propagation. Time itself does not pass slower in these materials; rather, it is the light wave's effective speed that is altered.
