Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...

Based on: Refraction, and How to Refract. Including Sections on Optics, Retinoscopy, the Fitting of Spectacles and Eye Glasses, etc. By James Thorington, A.M., M.D., Professor of Diseases of the Eye ...

Nearly a decade after getting waves of light to bend backward, physicists have done the same with electrons. Electrons coursing through a sheet of carbon atoms exhibited negative refraction, bending ...

If a newborn calf fails to receive the right quantity and quality of colostrum quickly enough after birth it is four times more likely to die and twice as likely to succumb to infection. Feeding ...

A refractometer is a device used to measure the refractive index (n) of a substance. In this article, we discuss what a refractometer is and how it works, the different types available and their ...
