లెన్ సూత్రం:
గణనలు:
\(P={1\over f}\)
\(f={1\over P}={1\over5}=0.2m=20cm\)
\({1\over f}={1\over v}-{1\over u}\)
\({1\over 20}={1\over v}-{1\over -10}\)
\({1\over v}={1\over 20}+{1\over -10}={1-2\over20}\)
\(v={-20\over 1}=-20cm\)
లెన్స్ యొక్క మాగ్నిఫికేషన్ మనకు తెలుసు:
\(m={di\over do}={v\over u}\)
\({di\over 6}={-20\over -10}=2\)
\(di=6*2=12cm\)
కాబట్టి, చిత్రం యొక్క వ్యాసం 12 సెం.మీ.
