WebA refractive index is a property of the material itself. Now an effective refractive index can be given for an optical component (e.g. a waveguide) as a measure of the overall delay of a light beam in that component. This is not a property of the material the optical fibre is made of, but an effective property of the optical fibre altogether ... WebThe speed of light changes as it moves between media.
