why do star appear in twinkling of star
Answers
Answer:Stars do not really twinkle, they just appear to twinkle when seen from the surface of Earth. The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities.
Answer:
Stars are at much height in the space when star's light travel to come to us it's cover a long distance in our atmosphere and Earth's atmosphere consists many layers with variations of refractive indexes .
So when star's light travel from a medium of higher refractive index to a lower one and a lower one to higher one it's path changes continuously.
As the path of light changes continuously it appears to be twinkling.
