Umthetho womfanekiso weConvex lens
Kwi-optics, umfanekiso owenziwe kukudibana kokukhanya kokwenyani ubizwa ngokuba ngumfanekiso wokwenyani;ngenye indlela, ibizwa ngokuba ngumfanekiso wenyani.Ootitshala abanamava befiziksi bahlala bekhankanya indlela enjalo yokwahlula xa bechaza umahluko phakathi komfanekiso wokwenyani kunye nomfanekiso obonakalayo: “Umfanekiso wokwenyani ngu...Funda ngokugqithisileyo -
Yintoni ukugqwethwa kweelensi?
Le yingxaki ngaphakathi kwendawo ye-optics, enenkcazelo yayo esemgangathweni kwi-optics.Umfanekiso oveliswe ngokuthatha ifoto ngekhamera uya konakala.Umzekelo, sonke sinamava okuthatha imifanekiso ngeekhamera eziqhelekileyo ekhaya.Kukho uhlobo lwelensi ebizwa ngokuba “...Funda ngokugqithisileyo -
