Question
Twinkling of stars is due to atmospheric
Options
dispersion of light by water droplets
refraction of light by different layers of varying refractive indices
scattering of light by dust particles
internal reflection of light by clouds
Solution
refraction of light by different layers of varying refractive indices
Explanation -
Due to the refraction of light by different layers of varying refractive indices, the apparent position of the source of light keeps on changing.
Due to this, stars appear to twinkle.
