Q. Consider the following statements regarding the apparent twinkling of stars near the horizon:
  1. The atmosphere is denser at the horizon, causing increased twinkling of stars close to it.
  2. The energy output from stars varies frequently, leading to enhanced twinkling near the horizon.
Which of the above statements is/are correct?

Answer: Only 1 is correct
Notes: Stars twinkle more near the horizon because their light passes through a denser and more extensive part of the Earth's atmosphere, which refracts the light more strongly, creating the twinkling effect. The variation in a star's intrinsic energy output does not cause twinkling; therefore, only statement 1 is correct, not statement 2.
