DON'T MISS THE 3 PRACTICE PROBLEMS AT THE END. UNDERSTANDING THE TWO IMPORTANT OBJECTIVE PROBLEMS HELPS US UNDERLINE HOW HUMAN EYE PERCEIVES IMAGES
Q : When the Sun is behind dark clouds and there are gaps in the clouds, you will often see sunlight ""fanning"" out from the gaps as shown in the given photograph. Though the rays are closely parallel but we see them diverging as they approach the earth. Which of the following statements most suitably explains this effect?
 (a)Distant objects appear smaller than nearer objects. 
 (b)Sunrays are actually radiated from the sun radially.     
 (c) Light bends at sharp corners of opaque object that it encounters.  
 (d)The  gaps  work  as light  sources at finite  distance hence  radiate diverging light
