👉 A refractometer is a device that measures and displays the angle of refraction. It works by observing the angle of deviation between two media or surfaces when light passes through them at different speeds, often measured in degrees or radians. The term "refractometer" refers to a device used for measuring angles of refraction in the optical spectrum. Refractive indices are fundamental constants that describe how light behaves under different conditions. In optics, refractive indices can be related to the speed of
