Refractive Index A refractometer measures the extent to which light is bent i e refracted when it moves from air into a sample and is typically used to determine the index of refractionrefractive index or n of a liquid sample The refractive index is a unitless number, between 1 3000 and 1 7000 for most compounds, and is

The refractive index or index of refraction of a medium is a measure for how much the speed of light or other waves such as sound waves is reduced inside the medium For example, typical soda-lime glass has a refractive index of 1 5, which means that in glass, light travels at $ 1/1 5=0 67 $ times the speed of light in a vacuum Two common properties of glass and other transparent materials
