Ok i get that hotter air is less dense , but when light goes from hot air to colder air we are dealing with the same atoms it is just that the photon will have less collisions , why would the angle of re-emission change for the photon just because it is having less or more collisions in the medium. As the photon gets absorbed and re-emitted , why would this cause refraction just because the atoms are close together and then far apart how does this change the angle that the photon gets re-emitted out of the atom .
