Introduction. The bending of a light ray as it passes from air to water is determined by Snell's law. This law also applies to the bending of light by lenses and to the guiding of light by the fiber optic cables that carry modern communications signals. In part 1 of this lab you will determination of the differential refractive index. All other methods e.g. the determination by using polarisation microscopy or calculation via Gladestone Dale or Lorentz-Lorenz equation, were not carried out. Either due to a lack of the required instruments (polarisation microscope), other missing parameters (refractive Back to index. ?. ?. Refractive Index and Dispersion.

Traditionally optical glasses in the range of ?d . coefficients of the absolute refractive indices can be calculated for other temperatures and wavelengths values with the aid of Equation (11).

Mathematically its definition is n = c v. , where c is the speed of light in a vacuum, and v is the ve- locity of light in the material. Material. Refractive Index. Air. 1.0003. Water. 1.333.

Specular reflection at a curved surface forms an image which may be magnified or demagnified. We will shortly return to the subject of curved mirrors and geometric In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how light propagates through that medium. It is defined as. Refractive index is a dimensionless physical quantity, which is specific for a certain medium, and its value characterizes the speed of light in this medium. We distinguish between the relative and absolute refractive index. Relative refractive index is defined as a ratio of speeds of light in two different media. If we define the normal as being the perpendicular line to the surface of the interface, then a higher value of refractive index will mean that the ray bends more towards the normal when passing from the vacuum to the medium. Most refractive index values using visible light waves are between 1 and 2 whilst refractive index refractometry ::: A refractometer is the instrument used to measure the refractive index of materials. What is refractive index? The refractive index of a medium is a measure of how much the speed of light is reduced i$
