How to star appear their actually position |
| Answer» \tThe twinkling of stars is also due to atmospheric refraction.\tThe air in the earth\'s atmosphere is such that it has increasing refractive index\tWhen starlight enters earth\'s atmosphere it undergoes multiple refraction continuously before it reaches the earth .\tBecause of the increasing refractive index, the starlight bends downwards (ie towards the normal) and thereby the apparent position of the star is slightly higher than its actual position. | |
