Twinkling of stars is occurred due to which phenomenon?

A. Refraction

B. Total Internal Reflection

C. Both A & B

D. Tide Waves

The 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.

The atmospheric refraction is the phenomenon that is the reason for the twinkling of stars. The air that is present in the atmosphere is a dense fluid that is spread out over the region. It is responsible for bending of the light beam that comes through the stars.
