Question

atmospheric refraction.....​

Answer 1

Explanation:

Atmospheric Refraction....

Refraction which takes place from Earth's atmosphere is called atmospheric refraction.

Different layers of Earth's atmosphere have different densities. Hence when light passes from it , it gets refracted .

Application of atmospheric refraction.

Twinkling of stars.....

In fact stars does not twinkle , they appear twinkling bcz of atmospheric refraction . When the star light passes from Earth's atmosphere it gets refracted and the star twinkles.

Planet does not twinkle bcz they don't have the light of their own . They are closer to the Earth , they are extending source of light and they nullify twinkling effect.

Answer 2

$\huge\underline\mathfrak\red{Answer}$

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. This refraction is due to the velocity of light through air, decreasing with increased density.
