Answer:
The most appropriate correct answer to the given question is option A.
Explanation:
- Stars will not twinkle if they are viewed from the moon's surface it is because we know that the moon lacks an atmosphere.
- Additionally, the refraction of starlight by the atmosphere is what causes stars to twinkle. The multiple layers of the atmosphere cause the refractive indices to constantly change as a result of the star's light rays constantly changing their path.
- As an outcome the number of beams entering, the understudy of the eye continues changing with time and the stars seem to shimmer.
- We are able to see the twinkling stars just because of the effects of the Earth's atmosphere which makes the stars appear to be twinkling in the night sky.
- Winds in the atmosphere and regions with varying temperatures and densities influence starlight as it enters the atmosphere. When seen from the ground, this makes the star's light twinkle.
Hence, the statements given in the assertion and reason are true and the statement in reason (R) correctly holds the explanation for (A).
