একজন ছাত্র তার চোখ থেকে মাত্র ৮ সেন্টিমিটার দূরে বই রেখে ভালভাবে পড়তে পারে। তাকে স্বাভাবিক চোখের স্পষ্ট দর্শনের নিকটতম দূরত্বে বই রেখে পড়ার জন্য কত ক্ষমতার লেন্স ব্যবহার করতে হবে?

Created: 10 months ago | Updated: 9 months ago

আমরা জানি, লেন্সের ক্ষমতা D = $\frac{1}{f}$ এবং ফোকাস দূরত্ব = $f$

$∴ 1...> f = \frac{1}{v} + \frac{1}{u} = \frac{1}{- 8} + \frac{1}{25} = \frac{- 25 + 8}{200} = \frac{- 17}{\frac{200}{100}} = \frac{- 17 \times 100}{200} = - 8.5 m ∴ - 8.5 m ক্ষমতার লেন্স পড়তে হবে।Read more10 months ago 00বাংলাদেশ রেলওয়ে || বুকিং সহকারী (29-03-2019) সম্পূর্ণ বিষয় একত্রে01602. একটি কোণের মান তার পূরক কোণের মানের অর্ধেকের সমান। কোণটির মান কত?
