Question

What is Atmospheric Refraction.......???​

Answer 1

Explanation:

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 with increased density.

Answer 2

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

When light goes from one medium to another medium having different optical densities, then refraction of light rays (or bending of light rays) takes place. The refraction of light caused by the earth's atmosphere (having air layers of varying optical densities) is called atmospheric refraction.
