Surely. I don't want somebody think about me " changing the truths according to his way". This is true shape showing about refraction. But here is not a water and the atmospher isin't only an gas. There is more areas on the atmospher acting light and refracting it to a lot of possible directions. The shape is true on the atmospher but the opposite is true in the atmospher true too.
Some areas has more intense, and some areas have less intense, after that again a more intense area and less intense area. Somewhere on the atmospher is cold and later the light enters a hot area and later again cold area. So there is rising and falling humidity areas more than one. we don't know if the light coming closer or is moving away. as i have guessed it has %50 chance the light is moving away.
this is like if the system it is, it describes.
Notice: I edited first post by adding the descriptive figure.
Good on you for thinking of possible differences throughout the atmosphere! However, for light to refract away from the normal in the atmosphere (what you're arguing), the value of the refractive index ("n") must be lower than that of a vacuum, or less than one. n is determined by c/v
p through a substance. Only high energy X-Rays can have a phase velocity higher than that of light. Visible light, however, cannot. This confines its n to be higher in any medium than 1. In summation, when passing to a higher medium not of significant electromagnetic tendency, visible light will bend towards the normal, making it's light source appear slightly higher, as defined by the equation
n1*sin(θ1) = n2*sin(θ2).
(Basically that equation means, refraction is based on average atomic density, which in a vacuum is 1 atom per cm
3, and in air is 5 * 10
19 atoms per cm
3)
