Buyum fokus masofasi 20 sm bo'lgan sochuvchi linzadan 30 sm masofada turibdi. Tasvir linzadan qanday masofada hosil bo'ladi va u qanday?
- A)60 sm, haqiqiy
- B)12 sm, haqiqiy
- C)12 sm, mavhum
- D)60 sm, mavhum
π To'g'ri javob va tushuntirishni ko'rish
β C) 12 sm, mavhum
π‘ Sochuvchi linza uchun 1/f = β1/F β 1/d = β1/20 β 1/30 = β1/12, |f| = 12 sm, tasvir mavhum.
