WebThe refractive index, n, is dimensionless since it's a ratio. It has the formula n = c v, where c is the speed of light in vacuum and v is the speed of light in the medium. Both quantities have units of meters per second, m s. In a vacuum, the refractive index is unity, and all other media have a refractive index that is greater than one. WebAt 24 GHz, these authors measured the refractive index of dry carbon- dioxide-free air, nitrogen, oxygen, argon and carbon dioxide at mean temperature of 20°C and a mean pressure of 760 mm Hg, and reduced the measurements to 0°C.
