Question

what is atmospheric refraction​

Answer 1

Answer:

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. ... Astronomical or celestial refraction causes astronomical objects to appear higher above the horizon than they actually are.

Answer 2

Answer:

Hello mate ❣

Explanation:

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.

hope this helps u ✌✌
