Principle Of Refractometer

- Dec 08, 2018 -



When light enters another transparent medium from a transparent medium, it produces a refraction phenomenon caused by the different speeds of light in various media. Refractive index is the ratio of the speed at which light travels through air to the speed at which it travels in other materials.

Refractive index The ratio of the speed of light in air to the speed of light in the object or the sine of the angle of incidence of the angle of incidence of light from the object passing through the object at the D-line of the sodium spectrum at 20 °C. .
