Refractive index - Wikipedia

WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v. It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam. WebRefractive Index : n = 1.714-1.887: Refractive index varies depending on type of garnet: Distinguishing Features: High relief in thin section.
