Opal refractive index
WebIndex of Refraction. The speed of light in a transmitting medium is less than that of the speed of light in a vacuum. The index of refraction, n, is the ratio of the speed of light in a vacuum, c, to the speed of light in a medium, c': One consequence of this difference in speed is that when light goes from one medium to another at an angle ...

Most materials have a refractive index > 1 which means that light travels slower in a medium than it does in vacuum. The higher the refractive index, the slower the light moves in that medium. t shirt makers australiaWebAbstract.
