Ibanga lento lincane kunobude bokugxila belensi eqondile (do < f)
Ngokusekelwe ekubalweni kwe ukwakheka kwesithombe ngelensi eqondile, kungaphethwa ngokuthi ibanga lento (do) lincane kunobude be-focal (f) belensi eqondile, izakhiwo zesithombe yilezi:
– Okubonakalayo kusho ukuthi ukukhanya akudluli esithombeni
– Okuqondile
– Uma into ikude kakhulu nelensi eqondile, kulapho usayizi wesithombe uba mkhulu khona
– Uma into ikude kakhulu nelensi eqondile, isithombe siqhele kakhulu kunelensi eqondile.
Ibanga lento lilingana nobude be-focal lens ye-convex (do = f)
Ngokusekelwe ekubalweni kokwakheka kwesithombe ngelensi eqondile, kungaphethwa ngokuthi uma ibanga lento (do) lilingana nobude be-focal (f) belensi eqondile, khona-ke izakhiwo zesithombe yilezi:
– Okungokoqobo kusho ukuthi ukukhanya kudlula esithombeni
– Okuqondile
- Kukhulisiwe
– Isithombe sisebangeni elilinganiselwe
Ibanga lento likhulu kunobude bokugxila belensi eqondile (do > f)
Ngokusekelwe ekubalweni kokwakheka kwesithombe ngelensi eqondile, kungaphethwa ngokuthi uma ibanga lento (do) likhulu kunobude obuqondile (f) belensi eqondile, izakhiwo zesithombe yilezi:
– Okungokoqobo kusho ukuthi ukukhanya kudlula esithombeni
- Okuguquliwe
– Uma into ikude kakhulu nelensi eqondile, usayizi wesithombe uba mncane kakhulu.
– Uma into ikude kakhulu nelensi eqondile, isithombe siseduze nelensi eqondile
