In atmospheric applications, refractivity is defined as N = n – 1, often scaled as either N = 10 6 (n – 1) or N = 10 8 (n – 1); the multiplication factors are used because the refractive index for air, n deviates from unity by at most a few parts per ten thousand. Zobraziť viac In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive … Zobraziť viac The relative refractive index of an optical medium 2 with respect to another reference medium 1 (n21) is given by the ratio of speed of light in medium 1 to that in medium 2. This can be expressed as follows: Zobraziť viac Refractive index also varies with wavelength of the light as given by Cauchy's equation: The most general form of Cauchy's equation Zobraziť viac The refractive index of materials varies with the wavelength (and frequency) of light. This is called dispersion and causes prisms and rainbows to divide white light into its … Zobraziť viac Thomas Young was presumably the person who first used, and invented, the name "index of refraction", in 1807. At the same time he changed this value of refractive power … Zobraziť viac At the atomic scale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in the charges of each atom (primarily the Zobraziť viac When light passes through a medium, some part of it will always be absorbed. This can be conveniently taken into account by defining a complex refractive index, $${\displaystyle {\underline {n}}=n+i\kappa .}$$ Zobraziť viac
