At question 2 the answer should be assertion is wrong but reason is correct. Because eyes see infinity distance and more than 25 cm
Bruh if you read the thinks more than 25cm very keenly you may get defections on your eyes.And if eyes can see infinity distance,why can’t we see the places a 100kms away from your house.Use some logic.Also if we had a good eyesight then why can’t we see the bacteria.First tight the screw in you brain the answer the questions sensibly.
Option C is the right answer. The page has updated
What she said is actually correct! Practically, u feel that u couldn’t see till infinity but it’s just because there is something in front of ur eyes and that object blocks the object furthur to be seen and even if the path is clear, on Earth’s surface, you’re seeing through the atmosphere, and yellow particular matter in the air is scattering the light. In a vacuum, the human eye has no theoretical limit to how far it can see because light rays can travel an infinite distance. The human range of vision is infinite.
On a clear day, a person can see up to 3 miles before the horizon due to the curvature of the earth. However, skyscrapers can be seen further than 3 miles because there is no horizon obstruction. And the most comfortable distance at which one can read with a normal eye is about 25 cm. This distance is called the least distance of distinct vision.
So, technically she is correct and option no. D (Assertion is correct but reason is false) should be correct!!
