The most accurate way to do this simply would be to use the Brewster angle. You set up your sample with a laser that is polarized perpendicular to the surface; then you measure the reflection as a function of angle of incidence. You get a clear null in the reflection at just one angle - the Brewster angle. This is a simple enough experiment ...

The refractive index is used to measure solids, liquids, and gases. Most commonly it is used to measure the concentration of a solute in an aqueous solution . It can also be used as a useful tool to differentiate between different types of gemstone, due to the unique chatoyance each individual stone displays. 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 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 electrons) proportional to the electric susceptibility of the medium. (Similarly, 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 Thomas Young was presumably the person who first used, and invented, the name "index of refraction", in 1807. At the same time he … 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 is Usually, it is sufficient to use a two-term form of the … Zobraziť viac The refractive index of materials varies with the wavelength (and frequency) of light. This is called dispersion and causes prisms Zobraziť viac WebThe velocity of propagation of a electromagnetic wave through a solid is given by the frequency-dependent complex refractive index N = n - ik where the real part, n is related to the velocity, and k, the extinction coefficient is related to the decay, or damping of the oscillation amplitude of the incident electric field.The optical properties of the solid are …
