Question 1(viii)
Convex lens is used for the correction of long sightedness. Which of the following reasons support this statement?
P. The image of near by object falls behind the retina.
Q. The lens is too flat resulting in hypermetropia.
R. Uneven curvature of cornea.
- Only R
- Only Q
- Only P and R
- Only P and Q
Only P and Q
Reason — In hypermetropia, the lens becomes too flat and therefore the image is formed behind the retina. A convex lens corrects this problem.
Key Concepts Covered
This question tests your understanding of the following concepts from the chapter Solved Sample Paper 5: Question, Viii, Convex, Lens, Correction, Long. These are fundamental topics in Biology that students are expected to master as part of the ICSE Class 10 curriculum.
A thorough understanding of these concepts will help you answer similar questions confidently in your ICSE examinations. These topics are frequently tested in both objective and subjective sections of Biology papers. We recommend revising the relevant section of your textbook alongside practising these solved examples to build a strong foundation.
