WebRefractometry is an analytical method to measure the refractive index of a solid or liquid material. The 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 ... WebWhen X-rays are applied to a material's flat surface at grazing angles of incidence, total reflection will occur at or below a critical angle, θc. This angle is exceedingly small and is referred to as the critical angle. The angle varies depending upon the electronic density of the material. The higher the incident X-ray angle relative to the ... nabbed meaning in urdu
