(b) scattering of light by dust particles

(c) dispersion of light by water drops

(d) atmospheric refraction of starlight✅✅

⏭Twinkling of stars is due to atmospheric refraction of star light. OhThe 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 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. This causes the light from the star to twinkle when seen from the ground.
