Question

twinkling of stars is due to atmospheric refraction.' explain this statement with the help of a diagram and state the reason why planets do not twinkle​

Answer 1

Twinkling of stars is due to atmospheric refraction of star light. The star light after entering the earth's atmosphere undergoes refraction in a continuous manner before it reaches the Earth. The atmospheric refraction is due to change in the refractive index at different level in atmosphere. The star light bends towards the normal, the apparent position is different from the actual position of star. Since atmosphere is not stationary and keeps changing. As path of rays of light coming from star varies slightly then the apparent position of star also varies slightly and the amount of light entering the eye flickers. Sometimes, it is brighter and sometimes the star seems fainter. In this way, stars twinkle.

Answer 2

Answer:

Planets do not twinkle because:1. Planets are not a source of light. Instead, they reflect low intensity light reaching them. ... As the planets are closer, planets appear larger in comparison to the stars.
