Question

atmospheric refraction ​

Answer 1

Answer:

The refraction which caused by atmosphere is known as atmospheric refraction.

Generally this refraction is caused due to to presence of many layers in atmosphere

which refract the coming light due to change in density of every layer deviate the light from its original way very slightly and after passing through many of this type of layers the light debate by large distance which is called refraction.

Answer 2

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.
