Isihloko mayelana nezakhiwo zesithombe esakhiwe yisibuko esigobile
Ibanga lento lincane kunobude obuqondile besibuko esigobile (do < f)
Ngokusekelwe ekubalweni kokwakheka kwesithombe ngesibuko esigobile, kuphethwa ngokuthi uma ibanga lento (do) lincane kunobude obuqondile (f), khona-ke izakhiwo zesithombe yilezi:
– Okubonakalayo kusho ukuthi ukukhanya akudluli esithombeni
– Okuqondile
– Uma into ikude kakhulu nesibuko esigobile, kulapho ubukhulu besithombe bukhula khona
– Uma into ikude kakhulu nesibuko esigobile, isithombe sikude kakhulu nesibuko esigobile
Izinto ezitholakala endaweni egxile esibukweni esigobile (do = f)
Ngokusekelwe ekubalweni kokwakheka kwesithombe ngesibuko esigobile, kuphethwa ngokuthi uma into itholakala endaweni egxile esibukweni esigobile, izakhiwo zesithombe yilezi:
– Okubonakalayo kusho ukuthi ukukhanya akudluli esithombeni
– Okuqondile

– Okungokoqobo kusho ukuthi ukukhanya kudlula esithombeni
- Okuguquliwe
– Uma into ikude kakhulu nesibuko esigobile, usayizi wesithombe uba mncane kakhulu
– Uma into ikude kakhulu nesibuko esigobile, isithombe siseduze kakhulu nesibuko esigobile
Izinto ezitholakala enkabeni yokugoba (do = R)
Ngokusekelwe ekubalweni kokwakheka kwesithombe ngesibuko esigobile, kuphethwa ngokuthi uma into itholakala endaweni ephakathi yesibuko esigobile, izakhiwo zesithombe yilezi:
– Okungokoqobo kusho ukuthi ukukhanya kudlula esithombeni
- Okuguquliwe
– Usayizi wesithombe = usayizi wento
– Ibanga lesithombe = ibanga lento
Ibanga lento likhulu kunerediyasi yokugoba kwesibuko esigobile (do > R)
Ngokusekelwe ekubalweni kokwakheka kwesithombe ngesibuko esigobile, kuphethwa ngokuthi uma ibanga lento likhulu kune-radius yokugoba kwesibuko, izakhiwo zesithombe yilezi:
– Okungokoqobo kusho ukuthi ukukhanya kudlula esithombeni
- Okuguquliwe
– Uma into ikude kakhulu nesibuko esigobile, usayizi wesithombe uba mncane kakhulu
– Uma into ikude kakhulu nesibuko esigobile, isithombe siseduze kakhulu nesibuko esigobile
- Iyini imvelo yesithombe esakhiwe yisibuko esigobile lapho into ibekwe endaweni engapheli?
Isithombe singokoqobo, siphendukezelwe, futhi sinciphile kakhulu. Sakhiwe endaweni egxile kuyo isibuko esigobile.
- Chaza izici zesithombe esakhiwe yisibuko esigobile lapho into ibekwa ngale kwesikhungo sokugoba.
Isithombe esakhiwe singokoqobo, siphendukezelwe, futhi sinciphile. Sakhiwe phakathi kokugxila kanye nendawo ephakathi yokugoba.
- Kwenzekani esithombeni esakhiwe yisibuko esigobile lapho into ibekwa phakathi nendawo yokugoba?
Uma into iphakathi nendawo yokugoba, isithombe singokoqobo, siguquliwe futhi sinobukhulu obufanayo nento. Isithombe sakhiwa futhi phakathi nendawo yokugoba.
- Yiziphi izici zesithombe esakhiwe lapho into ibekwa phakathi kwesikhungo sokugoba kanye nokugxila esibukweni esigobile?
Kulesi simo, isithombe singokoqobo, siphendukezelwe futhi sikhulisiwe. Sakhiwe ngale kwesikhungo sokugoba.
- Iyini imvelo yesithombe esakhiwe lapho into ibekwe endaweni egxile kuyo esibukweni esigobile?
Isithombe sakhiwe singapheli futhi singokoqobo, siguquliwe, futhi sikhuliswe kakhulu.
- Isithombe esakhiwe yisibuko esigobile sishintsha kanjani lapho into ibekwa phakathi kwensika kanye nendawo egxilwe kuyo?
Uma into ibekwa phakathi kwesigxobo kanye nokugxila kwesibuko esigobile, isithombe esakhiweyo siba ngokoqobo, siqonde, futhi sikhulisiwe. Isithombe sakhiwa ngemuva kwesibuko.
- Usayizi wesithombe uqhathaniswa kanjani nosayizi wento lapho into ibekwe endaweni egxile kuyo esibukweni esigobile?
Uma into ibekwe endaweni egxile kuyo, usayizi wesithombe mkhulu kakhulu uma uqhathaniswa nosayizi wento, njengoba isithombe sakhiwe endaweni engapheli.
- Ingabe isibuko esigobile singakha izithombe zangempela kanye neze-virtual? Chaza ukuthi kungani.
Yebo, isibuko esigobile singakha izithombe zangempela neze-virtual. Uma into ibekwe phakathi kwensika kanye nokugxila, isithombe esakhiwe siba ngokoqobo, siqondile, futhi sikhulisiwe. Kuzo zonke ezinye izikhundla zento, isithombe singokoqobo futhi siguquliwe.
- I-mirror equation ihlobene kanjani nezakhiwo zezithombe ezakhiwe yisibuko esigobile?
Isibalo sesibuko esingu-1/f = 1/v + 1/u sihlobanisa ibanga lento (u), ibanga lesithombe (v), kanye nobude be-focal (f). Lesi sibalo sisiza ekubikezeleni indawo, uhlobo, kanye nosayizi wesithombe. Lapha, isibuko esigobile sinobude be-focal obungemuhle, into yangempela inebanga lento engemuhle, kanti isithombe sangempela sinebanga lesithombe elingemuhle.

Kubaluleke ngani ukukhuliswa komfanekiso ngokwesimo sesithombe esakhiwe yisibuko esigobile?
Ukukhulisa (m) kuchazwa njengesilinganiso sokuphakama kwesithombe (h₂) nokuphakama kwento (h₁), okungukuthi, m = -v/u = h₂/h₁. Uphawu olunegethivu lubonisa ukuthi isithombe siguquliwe. Uma |m| > 1, isithombe siyakhuliswa; uma |m| = 1, isithombe sinobukhulu obufanayo nento; futhi uma |m| < 1, isithombe siyancishiswa.
