Ukukhanya kunokuchazwa ngeendlela ezininzi.
Ifoton, ifom yamaza, isuntswana, i-electromagnetic frequency.Ukukhanya kuziphatha njengesuntswana elibonakalayo kunye namaza.
Into esiyicinga njengokukhanya yinxalenye encinci ye-electromagnetic spectrum eyaziwa ngokuba kukukhanya okubonakalayo komntu, apho iiseli zamehlo omntu zinovelwano.Uninzi lwamehlo ezilwanyana lunovelwano kuluhlu olufanayo.
Izinambuzane, iintaka, kunye neekati kunye nezinja zinokubona iqondo elithile lokukhanya kwe-UV, ngelixa ezinye izilwanyana zinokubona infrared;iintlanzi, iinyoka, kwaneengcongconi!
Ubuchopho besilwanyana esanyisayo butolika/buhlula ukukhanya kube 'kumbala'.Ubude bokukhanya okanye ukuphindaphindwa kokukhanya bubo obumisela umbala esiwucingayo.Umgama omde ukhangeleka ngathi ubomvu ngelixa ubude obufutshane bubonakala bubhlowu.
Ngoko umbala awukho kwindalo iphela, kodwa yindalo yeengqondo zethu.Imele kuphela iqhezu elincinci le-electromagnetic spectrum.Ifoton nje ngamaxesha athile.
Indlela esisiseko yokukhanya kukusinga kweefotoni, ezijikeleza kubude obuthile.
