Question

atmospheric refraction.....​

Answer 1

Step-by-step explanation:

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.

Answer 2

Atmospheric Refraction

the refraction of light caused by the earth's atmosphere( having a layers of varying optical densities) is called atmospheric refraction.

• phenomenon in nature occur due to the atmospheric refraction of light

1. twinkling of stars
2. the star seem higher than they are actually are.
3. advance sunrise and delayed sunset= we can see the sun about 2 minutes before the actual sunrise and 2 minutes after the actual sunset because of atmospheric refraction.
