Twinkling of stars is on account of:
- Alarge distance of stars and storms in air.
- Brotation of earth
- Clarge size of stars
- Dlarge distance of stars and fluctuations in the density of air.
Solution & Step-by-step Explanation
The twinkling of stars is caused by atmospheric refraction. As starlight passes through different layers of the atmosphere with varying densities and temperatures, the path of the light bends, leading to fluctuations in the apparent position and brightness.
