Best answer
Correct Answer - Option 1 : 4 डायॉप्टर

उत्तर व स्पष्टीकरण: 4 डायॉप्टर

बहिर्गोल भिंगाचे नाभीय अंतर उजवीकडे असल्याने धन असते. 

अंतर्गोल भिंगाचे नाभीय अंतर डावीकडे असल्याने ऋण असते.

डायॉप्टर हे भिंगाचे एकक आहे..

बहिर्गोल भिंगाचे नाभीय =f= अंतर 25 cm = 0.25 m.

भिंगाची शक्ती = P =?

P = 1/F.

= 1/0.25.

= 4 डायॉप्टर .
