Why do stars twinkle? ( say about density difference b/w the atmospheric layers and how this cause the twinkling of stars ).

plz do not copy from google. I need a clear answer. I can give you 40 points. Plz...

Answer 1

Heya !

Question -

Why do stars twinkle?

Answer -
1. The twinkling of a is star due to atmospheric refraction of star light .
2. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities.
3. Due to this fluctuations of refractive index of layers stars appear to twinkling.

Hope this helps you !

Answer 2

twinkling of stars is caused by the passing of light through different layers of a turbulent atmosphere. Most scintillation effects are caused by anomalous refraction caused by small-scale fluctuations in air density usually related to temperature gradients.
