WebNov 1, 2006 · Refractometry: Theory Theory The speed of light in a vacuum is always the same, but when light moves through any other medium it travels more slowly since it is constantly being absorbed and reemitted by the atoms in the material. WebRefractometry is an analytical method used to measure the refractive index of a sample to determine its composition or purity. Refractometry is a qualitative and non-destructive technique that is based on Snell's law. The refractometry method, which is largely used in industry for quality control purposes, uses a refractometer. flower on green dressesWeb2.0 Theory of Refractive Index (RI) The speed of light travelling through a vacuum is always the same. When light moves through another medium, its speed slows down because the light is being constantly absorbed and re‐emitted by atoms within the material through which the light is travelling.
