WebThe Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as v = c / n (1) where v = velocity of light in the medium (m/s, ft/s) c = speed of light in air or vacuum - approximately 3 108 m/s (or 299792458 m/s) n = refractive index WebThe refractive index of milk is sometimes used to indicate adulteration especially watering. The refraction of light by a solution depends upon the individual molecular substance present and upon their concentrations. The total refraction is sum of the individual refractions of the constituents present in the solution.
