define atmospheric refraction. how is it responsible for twinkling of stars?
Answers
Explanation:
In simple terms, twinkling of stars is caused by the passing of light through different layers of a turbulent atmosphere. ... Most scintillation effects are caused by anomalous atmospheric refraction caused by small-scale fluctuations in air density usually related to temperature gradients.
Hi Unnie,

Twinkling of stars: Twinkling of stars is due to atmospheric refraction of star light. The 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
