Kafushane, bese ... "Ukukhanya kwelanga, okusebenzisana nama-molecule omoya, kusakazeke ngemibala ehlukene. Kuyo yonke imibala, okuluhlaza okwesibhakabhaka yiyona ethambekele kakhulu ekusakazekeni. Kuvela ukuthi empeleni ithatha indawo yomoya. "
Manje ake sibhekisise
Izingane kuphela ezingabuza imibuzo elula kangangoba umuntu omdala ngokuphelele akazi ukuthi angayiphendula kanjani. Umbuzo ovame kakhulu ukuhlupha amakhanda ezingane: "Kungani isibhakabhaka siluhlaza okwesibhakabhaka?" Kodwa-ke, akuyena wonke umzali owazi impendulo eyiyo naye. Isayensi ye-physics kanye nososayensi abebezama ukuyiphendula iminyaka engaphezu kwekhulu bazosiza ukuyithola.
Izincazelo eziyiphutha
Sekungamakhulu eminyaka abantu befuna impendulo yalo mbuzo. Abantu basendulo babekholelwa ukuthi lo mbala uyintandokazi kaZeus noJupiter. Ngesinye isikhathi, incazelo yombala wesibhakabhaka yakhathaza izingqondo ezinkulu ezinjengoLeonardo da Vinci noNewton. ULeonardo da Vinci wayekholelwa ukuthi, ukuxhuma omunye nomunye, ubumnyama nokukhanya kwakha umthunzi okhanyayo - oluhlaza okwesibhakabhaka. INewton ihlotshaniswa noluhlaza okwesibhakabhaka nokuqongelelwa kwenqwaba yamaconsi amanzi esibhakabhakeni. Kodwa-ke, kwaba ngekhulu le-19 kuphela lapho kwafinyelelwa esiphethweni esifanele.
Ibanga
Ukuze ingane iqonde incazelo efanele isebenzisa isayensi ye-physics, okokuqala kudingeka iqonde ukuthi imisebe yokukhanya yizinhlayiya ezindiza ngejubane elikhulu - izingxenye zamaza e-electromagnetic wave. Emfudlaneni wokukhanya, imishayo emide nemifushane iyahambisana, futhi ibonwa ngeso lomuntu ndawonye njengokukhanya okumhlophe. Njengoba zingena emkhathini ngamaconsi amancane kakhulu amanzi nothuli, zisakazeka kuyo yonke imibala ye-spectrum (uthingo).
UJohn William Rayleigh
Emuva ngo-1871, isazi sefilosofi saseBrithani uLord Rayleigh wabona ukuncika kokuqina kokukhanya okusakazekile ebangeni lomkhathi. Ukusabalala kokukhanya kwelanga ngokungajwayelekile emkhathini kuchaza ukuthi kungani isibhakabhaka siluhlaza okwesibhakabhaka. Ngokomthetho kaRayleigh, imisebe yelanga eluhlaza okwesibhakabhaka isakazeke kakhulu kunamawolintshi nokubomvu, ngoba inebude obufushane.
Umoya oseduze kobuso bomhlaba futhi ophakeme esibhakabhakeni wakhiwa ngama-molecule, ahlakaza ukukhanya kwelanga okusaphezulu emkhathini womoya. Ifinyelela kumqapheli kuzo zonke izinhlangothi, ngisho nakude kakhulu. Umkhanyo okhanyayo wehluka kakhulu ekukhanyeni kwelanga. Amandla weyokuqala athuthelwa engxenyeni ephuzi ngokuluhlaza, kuthi eyesibili iye eluhlaza okwesibhakabhaka.
Ukukhanya kwelanga okuthe xaxa kuhlakazekile, umbala uzovela ubanda. Ukusabalalisa okuqine kakhulu, i.e. igagasi elifushane kakhulu liku-violet, ukuhlakazeka kwegagasi elide kubomvu. Ngakho-ke, ngesikhathi sokushona kwelanga, izindawo ezikude zesibhakabhaka zibonakala ziluhlaza okwesibhakabhaka, kanti eziseduze kakhulu zibonakala zibomvana noma zibomvu klebhu.
Ukuphuma nokushona kwelanga
Ngesikhathi sokuhwalala nokusa, umuntu uvame ukubona ama-pink kanye nama-orange esibhakabhakeni. Lokhu kungenxa yokuthi ukukhanya okuvela eLangeni kuhamba phansi kakhulu kuya ebusweni bomhlaba. Ngenxa yalokhu, indlela okudingeka ukuthi ukukhanya ihambe ngayo kusihlwa nasebusuku iyinde kakhulu kunasemini. Ngenxa yokuthi imisebe ihamba ibanga elide kunawo wonke emkhathini, ukukhanya okukhulu okwesibhakabhaka kuhlakazekile, ngakho ukukhanya okuvela elangeni nasemafwini aseduze kubonakala kubomvu noma kupinki kubantu.
