Refractometer

Refraction is the change in the velocity of a light wave that hits a surface as it passes from one medium to another with a different refractive index. The refractive index is the ratio between the speed of light in vacuum and the speed of light in another substance, is a physical property characteristic of each species (solid, liquid or gaseous) that is characterized by the propagation of light in a given medium. This parameter of analysis is a good approximation for media where losses by absorption or other phenomena are negligible.

The measuring instrument associated with this parameter is called a refractometer. Its operation is based on measuring the amount of curvature of light passing through the sample. The formula behind the phenomenon is Snell's law, which is often used to describe the relationship between angles of incidence and light.

Use of the Refractometer

Refraction is the change in the speed of light as it passes from one medium to another, which is manifested by the variation that occurs in the wave as it passes through the media (gaseous, liquid, solid). Light travels in different materials at different speeds, making the refractive index a specific physical property. The formula behind the phenomenon is described with the Snell Law, which is used to describe the relationship between the angles of incidence and light.
