Question 1: Crepuscular Rays and Perspective
Explanation
The sun is located at a very large distance from the Earth (approximately 150 million km). Consequently, the light rays reaching the Earth are practically parallel to each other.
The “fanning out” effect seen in the photograph is an optical illusion caused by linear perspective. This is the same phenomenon observed when looking at railroad tracks: although the tracks are parallel, they appear to converge at a vanishing point in the distance. Conversely, parallel rays coming from a distant source appear to diverge as they approach the observer.
Correct Option: (a) Distant objects appear smaller than nearer objects.
