Solution


Q.

Assertion: The image of a distant object is formed in front of the retina and not at the retina itself.
Reason: The excessive curvature of the eye lens is a defect of myopia.
1 Both assertion and reason are correct and reason is the correct explanation of assertion.  
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.  
3 Assertion is true, but reason is false.  
4 Assertion is false, but reason is true.  

Ans.

(1)

A person with myopia can see nearby objects clearly but cannot see distant objects distinctly. A person with this defect may see clearly up to a distance of a few metres. In a myopic eye, the image of a distant object is formed in front of the retina but not at the retina itself. This defect may arise due to excessive curvature of the eye lens. Thus, both assertion and reason are correct and reason is the correct explanation of assertion.
