... Let summarize it all. The refractive index of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical glass has a refractive index of 1.5, which means that light travels at 0.67 times the speed in air or vacuum. Tw ...
