Why do stars twinkle


Why do stars twinkle?    
(Ans) The twinkling of stars is due to atmospheric refraction of star-light. The atmosphere is made of several layers and the refractive indices which keep on changing continuously due to this path of light rays from the star keeps on changing their path continuously. As a consequence the number of rays entering, the pupil of eye goes on changing with time and the stars appear twinkling.
