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 air depends on the air density and thus vary with air temperature and pressure. Since the pressure is lower at higher altitudes, the refractive index is also lower, causing light rays to refract towards the earth surface when traveling long distances through the atmosphere.
