The correct answer will be -
लेन्सची शक्ती +4.0 D असेल. The power of the lens will be +4.0 D.
Explanation:
Given in the question -
आता आपल्याला लेन्सची शक्ती शोधावी लागेल.
आपल्याला माहित आहे की लेन्सची शक्ती ही लेन्सच्या फोकल लांबीची परस्पर आहे.We know that power of the lens is the reciprocal of the focal length of the lens.
So, power of the lens = [tex]\frac{1}{focal\ length(in \ m)}[/tex]
Focal length = +25 cm = +0.25 m
Power of the lens = [tex]\frac{1}{0.25} = + 4.0\ D[/tex]
So,लेन्सची शक्ती +4.0 D असेल (the power of the lens will be +4.0 D).
