The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the index of refraction then allows the concentration to be determined using mixing rules such as the Gladstone–Dale relation and Lorentz–Lorenz equation. Refraction is a phenomenon when a ray of light traveling through a medium changes (bends) its direction upon entering into another medium. The two media are separated by an interface through which the ray enters the . A refractometer is a scientific instrument used to gauge a liquid's index of refraction. The refractive index is determined by placing a liquid sample on a prism and allowing light to pass through them to create a visible .

Definition: REFRACTION. The changing of a light ray’s direction (loosely called bending) when it passes through variations in matter is called refraction. SPEED OF LIGHT. The speed of light \(c\) not only affects refraction, it is one of the central concepts of Einstein’s theory of relativity. As the accuracy of the measurements of the .Digital refractometers often feature built-in temperature compensation and user-friendly interfaces, making them suitable for laboratory use and quality control applications. Abbe Refractometers.

Refraction is a phenomenon when a ray of light traveling through a medium changes (bends) its direction upon entering into another medium. The two media are separated by an interface through which the ray enters the second medium. Refraction is a commonly occurring everyday phenomenon.
