கொடுக்கப்பட்டுள்ளவை:
\(f=18cm\)
\(u=12cm\)
சூத்திரம்:
ஆடிச்சூத்திரம்: \({1\over f}={1\over u}+{1\over v}\)
உருப்பெருக்கம்: \(m={-v\over u}\)
கணக்கீடுகள்:
\({1\over f}={1\over u}+{1\over v}\)
\({1\over 18}={1\over 12}+{1\over v}\)
\({1\over v}={1\over 18}-{1\over 12}\)
\({1\over v}={12-18\over 12*18}={-6\over216}\)
\(v={-216\over6}=-36cm\)
எனவே, நாம் பெறுவது \(m={-v\over u}\)
\(m={-(-36)\over 12}=+3\)
எனவே, ஆடியால் உருவாக்கப்படும் உருப்பெருக்கம் +3.
