http://walter.bislins.ch/bloge/index.asp?page=Deriving+Equations+for+Atmospheric+Refraction WebOct 10, 2024 · Atmospheric Refraction. As light travels from outer space into the atmosphere, the air density rises, and hence the refractive index changes. As a result, the degree of refraction rises as light passes through the atmosphere, causing the light to take a “curved” route rather than a straight path as it would in a homogenous medium like glass.
