Explain atmospheric refraction

WebA mirage is an optical phenomenon that creates the illusion of water and results from the refraction of light through a non-uniform medium. Mirages are most commonly observed on sunny days when driving down a roadway. As you drive down the roadway, there appears to be a puddle of water on the road several yards (maybe one-hundred yards) in ...

Webabout refraction in air, or if he conceived of any kind of atmospheric structure, this information has been lost. We can thus conclude that refraction in transpar-ent media … Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased density. Atmospheric refraction near the ground produces mirages. Such refraction can … Webrefractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another.
