You are at one end of long airport runway. A vertical temperature gradient in the air results in the refractive index variation with height as n = n1( 1+ ay) where n1 is the refractive index at the runway
a = 1.5 * 10^(-6) per metre . Your eyes are at a height h=1.7m .
Beyond what distance you cannot see the runway?
