Lapho ubheka kuisibuko, ungazibona wena noma imvelo ezungeze isibuko ngokuzindla.Kodwa uyini umbala weqiniso weisibuko?Lona ngumbuzo othokozisayo ngempela, ngoba ukuwuphendula kudinga ukuthi singene sijule kweminye i-optical physics ethokozisayo.
Uma uphendule ngokuthi “isiliva” noma “awunambala”, kusho ukuthi unephutha.Umbala weqiniso wesibuko umhlophe nge-hue eluhlaza okhanyayo.
Nokho, ingxoxo ngokwayo icashile.Phela, ama-T-shirts angaba mhlophe namathoni aluhlaza, kodwa lokho akusho ukuthi ungawasebenzisela izikhwama zezimonyo.
Njengoba ukukhanya kuvela entweni kuya ku-retina yethu, singakwazi ukubona uhlaka nombala wento.Ubuchopho-ke bube bumisa ukwaziswa okuvela kuyi-retina-ngendlela yamasignali kagesi-kube yizithombe ukuze sizibone.
Into ekuqaleni ishaywa ukukhanya okumhlophe, okuyimini engenambala.Lokhu kubandakanya wonke amaza obude be-spectrum ebonakalayo yokuqina okufanayo.Amanye alawa maza amaza ayamuncwa, kanti amanye ayabonakala.Ngakho-ke, ekugcineni sibheka lawa maza amaza abonakalayo e-spectrum njengemibala.
Uma into imunca wonke amaza okukhanya abonakalayo, sicabanga ukuthi imnyama, futhi into ebonisa wonke amaza okukhanya abonakalayo ibonakala imhlophe emehlweni ethu.Eqinisweni, ayikho into engamunca noma ibonise ukukhanya kwesigameko 100% -lokhu kubalulekile uma kuhlukaniswa umbala wangempela weisibuko.
Akuzona zonke izifanekiso ezifanayo.Ukubonakaliswa kokukhanya nezinye izinhlobo zemisebe kagesi kungahlukaniswa kube izinhlobo ezimbili ezihlukene zokubonisa.I-specular reflection ukukhanya okubonakala nge-engeli ukusuka endaweni ebushelelezi, kuyilapho ukubonakaliswa okusabalele kukhiqizwa indawo emagebhugebhu ebonisa ukukhanya kuzo zonke izinhlangothi.
Isibonelo esilula sezinhlobo ezimbili zokusetshenziswa kwamanzi yidamu lokubuka.Uma indawo yamanzi izolile, ukukhanya kwesigameko kuboniswa ngendlela ehlelekile, okuholela esithombeni esicacile sendawo ezungeze ichibi lokubhukuda.Kodwa-ke, uma amanzi ephazanyiswa amadwala, amagagasi azobhubhisa ukubonakaliswa ngokusakaza ukukhanya okubonisiwe kuzo zonke izinhlangothi, ngaleyo ndlela asuse isithombe sendawo.
Iisibukowamukela isibuko reflection.Uma ukukhanya okumhlophe okubonakalayo kwenzeka endaweni yesibuko nge-engeli yesigameko, kuzovezwa kubuyiselwe esikhaleni nge-engeli ekhanyayo elingana ne-engeli yesigameko.Ukukhanya okukhanya phezuisibukoayihlukaniswa ngemibala eyisisekelo, ngenxa yokuthi "ayigobile" noma ayiphikisiwe, ngakho-ke wonke ama-wavelength aboniswa nge-engeli efanayo.Umphumela uyisithombe somthombo wokukhanya.Kodwa ngenxa yokuthi ukuhleleka kwezinhlayiya zokukhanya (ama-photons) kushintshwa yinqubo yokubonisa, umkhiqizo uyisithombe sesibuko.
Nokho,izibukoazimhlophe ngokuphelele ngoba izinto abazisebenzisayo aziphelele.Izibuko zesimanjezenziwa ngokucwenga isiliva noma ngokufafaza ungqimba oluncane lwesiliva noma i-aluminium ngemuva kweshidi lengilazi.I-quartz glass substrate ikhombisa ukukhanya okuluhlaza kakhulu kunamanye amaza obude, okwenza ukuthi kubonakaleisibukoisithombe sivele siluhlaza.
Lo mbala oluhlaza kunzima ukuwubona, kodwa ukhona.Ungakwazi ukubona ukusebenza kwawo ngokubeka amabili aqondaniswe ngokupheleleizibukozibhekene ukuze ukukhanya okuveziwe kukhombisana ngokuqhubekayo.Lesi simo sibizwa ngokuthi "i-mirror tunnel" noma "infinity mirror".Ngokocwaningo olwenziwa isazi sesayensi yemvelo ngo-2004, “lapho singena sijula emhubheni wesibuko, umbala wale nto uba mnyama futhi ube luhlaza.”Isazi se-physics sithole ukuthi isibuko sinobude obuphakathi kwama-nanometers angu-495 no-570.Ukuchezuka, okuhambisana nokuluhlaza.
