WebA typical value for the refractive index of air at sea level under standard atmospheric conditions is no = 1.000278. Since it is so close to 1, the difference between the refractive index of air and that in a vacuum ( n = 1) is of most interest. Since n−1 is very small, it is useful to define Refractivity, which is equal to:
