stars appear to be slightly higher in the sky than they actually are why is it so
Answers
Answer:
due to atmospheric refraction
Explanation:
the light coming from the stars bends slightly such that the stars appears nearer as they actually are
Answer- The above question is from the chapter 'Human Eye and the Colourful World'.
Given question: Stars appear to be slightly higher in the sky than they actually are. Why is it so?
Answer: Stars appear to be slightly higher in the sky than they actually are because:-
1. When light appears to enter the atmosphere from vacuum, it undergoes refraction and bend towards normal.
2. As we move towards Earth, the density of air keeps on increasing.
3. Thus, light keeps on bending as it moves from rarer to denser medium.
4. When light reaches our eyes, we can only see straight-line path.
5. Hence, stars appear at a different position which is also at a higher position.
