Kwiintsuku ezininzi nakwiindawo ezininzi, isibhakabhaka ngaphezulu komphezulu woMhlaba sibonakala siluhlaza. Kodwa khawucinge ngoku: Ngaba isibhakabhaka sihlala silombala? Kuthiwani ngeentsuku ezingwevu, okanye ukukhanya kokusa okunomsobomvu, okanye isibhakabhaka esibomvu ebusuku kuloo ngoma yendlela enye?

Impendulo ku- Kutheni isibhakabhaka siluhlaza? isebenza ngokufanayo 'Kutheni ikhona imibala?' Umbala ulula njengoko sikwazi ukuwubona. Isibhakabhaka sinemibala emininzi (eyintloko phakathi kwayo, eluhlaza okwesibhakabhaka) kuba inelanga lokukhanya.

Ukukhanya okubonakalayo luhlobo lwemitha ye-electromagnetic-isilayidi esincinci samandla abanzi afaka amaza erediyo, ii-microwaves, ukukhanya kwe-ultraviolet, i-x-reyi, kunye nemitha ye-gamma- enokubonwa liliso lomntu ngamehlo. Ukukhanya okumhlophe okuphuma elangeni, yindibaniselwano yabo bonke ubude obahlukeneyo bamaza ombane esikwaziyo ukuwabona.

Umbala ubonakala xa amehlo ethu ebhalisa kuphela ezinye- kodwa ayizizo zonke - zeevelengths esinokuzibona. Ukukhanya okubomvu, umzekelo, lelona liza licothayo libonakalayo kuthi: amandla ahamba ixesha elide kwaye anganyibiliki. Umbala oluhlaza okwesibhakabhaka, kwelinye icala, ngowona ukhawulezayo: amandla angcangcazelayo kwisingqisho esikhawulezayo nesikhawulezayo.

Isibhakabhaka sitshintsha umbala njengokukhanya okumhlophe okuvela elangeni kubetha umoya ojikeleze umhlaba kwaye kusabela ngeendlela ezahlukeneyo. Amaza okukhanya —kunye nawo onke amandla ombane wombane — aya kuhamba ngokuthe nkqo ngaphandle kokuba aza kubetha into. Amaza angabonakaliswa (njengesibuko), agobe (njengakwiprism), okanye asasazeke (njengasesibhakabhakeni).

Nangona isibhakabhaka (a.k.a air) sihlala sikhangeleka ngathi asibonakali emehlweni ethu, bubukho obuhle kakhulu, umxube oguqukayo nobunzima weegesi kunye namasuntswana. Ukukhanya okumhlophe, ukusuka elangeni uye emehlweni ethu, kufuneka kubhabhe kumjikelo weemolekyuli ezingenakubalwa kumoya wethu wokuqala.

Ukuxhamla uninzi zizinto esele zikhona jittery blue wavelengths. Ngenxa yeencopho zayo ezimfutshane, ezincinci kunye neentlambo, kunokwenzeka ngakumbi kunamanye amaza ukubetha umqobo kwaye usasazeke kuwo onke amacala. Ngenxa yoko, isibhakabhaka ngokuthe ngqo ngaphezulu kwayo nayiphina inqaku kumphezulu woMhlaba siya kujongeka siluhlaza okwesibhakabhaka ngaphezu kwesibhakabhaka esibonwe ngaphezulu komda okude. Ukuya phezulu kumphezulu weatmosfera, ukukhanya okuluhlaza okwesibhakabhaka okubonakala kakhulu kuba luhlobo lokuqala lwamandla ombane ukusasaza.

Ukuya emazantsi, ukukhanya okubonakalayo kuye kwahluzwa ngumoya ongaphezulu, kwaye uninzi lwayo lusasazekile. Ngaphandle kwamaza aluhlaza okwesibhakabhaka kodwa obomvu, orenji, tyheli, luhlaza, indigo, kunye namaza e-violet ajikeleza, ukukhanya okuxubileyo kuvela kumhlophe kwakhona: ukudityaniswa kwawo onke.

Nokuba ujonge esibhakabhakeni sasemini yimbumba egqibeleleyo ye-robin eluhlaza okwesibhakabhaka, ukutshona kwelanga okunemisonto enomsila, enomsila obomvu, okanye emva kwemini engwevu- konke kukukhohlisa kokukhanya.

Kwaye loo maqhinga ayenzeka nje ukuba enze izinto ezithile (kunye neefoto) ezintle kakhulu kwaye kufanelekile ukuba zihambe ngokwazo. Ukusuka eSantorini ukuya eMalibu, jonga ukutshona kwelanga kombane sicebisa ukuba uwele umhlaba ukuze ubone.
