Refractive index of solids
WebThe refractive index is the ratio of the velocity of an electromagnetic wave in vacuum relative to its velocity in the material of interest. Refractive index can be measured between 1.30 and 1.71 at a wavelength of 589.3 nm, using an Abbe refractometer. Ideal Uses of Refractometry Liquids Glasses Plastics, polymer films WebDegrees Brix (symbol °Bx) is a measure of the dissolved solids in a liquid, and is commonly used to measure dissolved sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass.If the solution contains dissolved solids other than pure sucrose, …
