Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF\(do=6cm,u=-10cm\) வில்லையின் திறன் +5.0 D.
சூத்திரம்:
வில்லையின் திறன்: \(P={1\over f}\)
ஆடி சூத்திரம்: \({1\over f}={1\over v}-{1\over u}\)
கணக்கீடு:
\(P={1\over f}\)
\(f={1\over P}={1\over5}=0.2m=20cm\)
\({1\over f}={1\over v}-{1\over u}\)
\({1\over 20}={1\over v}-{1\over -10}\)
\({1\over v}={1\over 20}+{1\over -10}={20-10\over200}\)
\(v={200\over 10}=20cm\)
நாம் அறிந்த படி வில்லையின் உருப்பெருக்கம்:
\(m={di\over do}={-v\over u}\)
\({di\over 6}={-20\over -10}=2\)
\(di=6*2=12cm\)
எனவே, பிம்பத்தின் விட்டம் 12 செ.மீ.
