Atmospheric Refraction
================================
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
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.
