Uma into ibekwa phambi kobuso besibuko obugobile obubonisa ukukhanya, isibuko esigobile sizokwakha isithombe sale nto. Uma indawo yento phambi kwesibuko esigobile yaziwa, udweba kanjani ukwakheka kwesithombe sento? Ukuze kucaciswe lokhu, ake sithi into yiba phambili isibuko esigobile njengoba kuboniswe esithombeni esingezansi.
Isihlokwana:
Umugqa o-orenji = isibuko esigobile
Umugqa oluhlaza okwesibhakabhaka = i-axis eyinhloko
Umcibisholo (oluhlaza okotshani) = into
R = isikhungo sokugoba kwesibuko esigobile
f = ukugxila kwesibuko esigobile
Isithombe sesithunzi sento singavezwa ngokusidweba sonke. ukukhanya ezidlula entweni, kodwa lokhu akunakwenzeka ngoba kuzoba nemigqa eminingi emele imishayo yokukhanya. Ukuze kube lula, kukhethwa imishayo yokukhanya embalwa nje ukuze imele yonke imishayo yokukhanya edlula entweni. Uma sibheka ukuthi lesi senzakalo sihilela ukukhanya okukhanyayo ufulawa umthetho wokubonakaliswa kokukhanya kumele kulandelwe lapho kudweba ukwakheka kwesithunzi.
Imisebe emithathu yokukhanya noma imisebe ekhethekile yezibuko ezigobile
Ukukhanya okukhethekile 1:
Umsebe 1 noma umsebe wokukhanya 1 oza esibukweni esigobile uboniswa njengohambisana no i-axis eyinhloko bese ithinta unqenqema oluphezulu lwento, bese iboniswa yisibuko esigobile lapho umsebe wokukhanya oboniswayo kufanele udlule khona indawo yokugxila (f)Imisebe yesigameko kanye nemisebe ebonisiwe eboniswayo kumele igcwalise umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokubonakalisa.
Ukukhanya okukhethekile 2:
Umsebe 2 noma umsebe wokukhanya 2 oza esibukweni esigobile uboniswa njengodinga ukudlula indawo yokugxila bese ithinta ingxenye ephezulu yento, bese iboniswa yisibuko esigobile lapho umsebe wokukhanya oboniswayo kumele uhambisane ne-axis eyinhloko. Umsebe wesigameko nomsebe oboniswayo oboniswayo kumele uhlangane umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokubonakalisa.
Ukukhanya okukhethekile 3:
Umsebe 3 noma umsebe wokukhanya 3 oza esibukweni esigobile uboniswa njengodinga ukudlula iphuzu eliphakathi lokugoba kwesibuko (R) bese ithinta unqenqema oluphezulu lwento, bese iboniswa yisibuko esigobile lapho umsebe wokukhanya oboniswayo uhambisana khona ukukhanya okungenayoImisebe yesigameko kanye nemisebe ebonisiwe eboniswayo kumele igcwalise umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokubonakalisa. Uma ukukhanya kwesigameko kuhambisana nomsebe wokukhanya obonakalayo khona-ke umsebe wokukhanya kumele ube ngoqondile (90o) enobuso besibuko obugobile lapho kudlula khona umsebe wokukhanya ukuze i-engeli yokwenzeka ibe ngu-90o ilingana ne-engeli yokubonakaliswa engu-90o.
Ukwakheka kwesithunzi (imisebe emibili ekhethekile)
Ukwakheka kwesithunzi sento kungaboniswa kusetshenziswa imishayo yokukhanya emibili kuphela, njengoba kuboniswe esithombeni esingezansi. Uma kusetshenziswa imishayo yokukhanya emibili noma imisebe emibili ekhethekile, kunezithombe ezintathu ezingaba khona zokwakheka kwesithunzi.
Imisebe ekhethekile 1 no-2
Imisebe ekhethekile 1 no-3
Imisebe ekhethekile 2 no-3
Isithombe sokwakheka kwesithunzi sento kusetshenziswa imisebe emibili yokukhanya sidinga ukulungiswa ukuze silingane nebanga lento esuke kuyo. isibuko esigobileUma ibanga lento esibukweni esigobile linjengasesithombeni esingenhla, kunezindlela ezintathu zokudweba ukwakheka kwesithombe usebenzisa imisebe yokukhanya emibili kuphela. Uma ibanga lento esibukweni esigobile lihlukile esithombeni esingenhla, isibonelo, into iphakathi kwephuzu eligxile kanye nendawo ephakathi yokugoba, khona-ke azikho izindlela ezintathu zokudweba ukwakheka kwesithombe, kungase kube nezindlela ezimbili kuphela zokudweba.
Uma udweba ukwakheka kwesithombe ngesibuko esigobile, ungakhetha indlela eyodwa futhi akudingeki usebenzise izindlela ezimbili noma ezintathu.
Ukwakheka kwesithombe (imisebe emithathu ekhethekile)
Ukwakheka kwesithunzi sento kungaboniswa kusetshenziswa imisebe yokukhanya emithathu noma imisebe emithathu ekhethekile, njengoba kuboniswe esithombeni esingezansi.
Uma ibanga lento esuka esibukweni esigobile lingafani nesithombe esingenhla, isibonelo into iphakathi kwesibuko esigobile nendawo eqondile, noma into iphakathi kwendawo eqondile nendawo ephakathi kwesibuko esigobile, khona-ke akuqiniseki ukuthi ukwakheka kwesithombe sento kungachazwa kusetshenziswa amathuba amathathu noma izindlela ezintathu njengoba kusesithombeni esingenhla. Kungenzeka ukuthi kunezindlela ezimbili kuphela noma izindlela ezimbili zokudweba ukwakheka kwesithombe. Sicela ubheke isibonelo sesithombe sokwakheka kwesithombe sento ngesibuko esigobile, lapho ibanga lento esuka esibukweni esigobile lihluka khona, esihlokweni. isithombe sesibuko esigobile.
