Twinkling of stars in clear sky during nighttime can be explained with
- Arefraction of light
- Breflection of light
- Cpolarization of light
- Dinterference of light
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (a) refraction of light
Explanation
The atmosphere has layers of different temperature and density, hence different refractive indices.
Starlight bends repeatedly as it passes through this turbulent air – atmospheric refraction.
Continuous changes in apparent position and brightness make stars appear to twinkle.
