Yini uthingo? Kwenzeka kanjani kusuka?

Rainbow - omunye amazing kakhulu nenqubo engokwemvelo. Yini uthingo? Kwenzeka kanjani kusuka? Lezi zinkinga abantu abanentshisekelo ngaso sonke isikhathi. Ngisho Aristotle wazama ukuchaza imfihlakalo yayo. Kunezinkolelo eziningi nama-legends ephathelene nayo (eya nezinye emhlabeni, isixhumanisi waphakanyiselwa emkhathini wezulu nomhlaba, iwuphawu ngobuningi, njll). Abanye abantu bakholwa ukuthi nguye ozokwenza ozoba ngaphansi rainbow, ukushintsha ubulili bayo.

Ubuhle bayo kuyabamangaza futhi uyakuthokozela. Kubuka ezimibalabala "ibhuloho magic", ngifuna ukukholelwa ezimangalisweni. Ukubukeka uthingo esibhakabhakeni azisa ukuthi isiphepho iphelile futhi sekuyisikhathi ngifike libalele.

Uthingo? It kungabonakala nasemkhakheni emvuleni noma ngemva eshaweni. Kodwa ukubukeka kwakhe akusona umbani ngokwanele nangokuduma. Kubonakala kuphela uma ilanga iphula phakathi kwamafu. Sidinga izimo ezithile ukuqinisekisa ukuthi kungabonwa. Kufanele ube phakathi imvula (kufanele sibe phambili) futhi ilanga (emuva). Amehlo akho, uthingo futhi maphakathi ilanga kufanele kube ku umugqa owodwa, noma leli bhuloho imilingo ungaboni!

Ngiqinisekile abaningi baye baqaphela, kwenzekani lapho wokukhanya ukukhanya okumhlophe uwela phezu bubble noma onqenqemeni izibuko beveled. It ihlukaniswe yaba imibala ehlukahlukene (oluhlaza, blue, obomvu, ophuzi, onsomi, njll). Isifundo okuyinto ezidabula ugongolo singene imibala yayo abalekeleli ngokuthi i nezibhebhe. Futhi umfanekiso umugqa ezimibalabala - bohlu.

Ngakho-ke yini uthingo? It kuyinto lwalugobile spectrum band umbala ezakhiwe division of ugongolo ukukhanya lapho sidlula amathonsi (okuyinto kuleli cala kukhona iphrizimu).

Imibala bohlu solar ngendlela ethize. Ngakolunye uhlangothi - bomvu, bese orange, olandelayo - ophuzi, oluhlaza okotshani, blue, indigo, violet. Rainbow sibonwa, kuyilapho amaconsi emvula iwe ngokulinganayo futhi ngokuvamile. Ngokuvamile, le licace kuba. Ngakho, ngo-Iconsi lemvula kungakazukufika masinyane ezintathu izinqubo: kwalungiswa izinkunga zokubona, ukucabangisisa ukusatshalaliswa ukukhanya.

Lapho ukubona rainbow? Emithonjeni, izimpophoma, lehla kungemuva, sprayable ukuthambisa umshini , njll indawo yayo esibhakabhakeni incike ekhomba lapho ilanga lingakhona. Ungajabulela yonke imibuthano elikhanyayo uma ukuba phezulu ngaphakathi the bhakabhaka. Ayanda ilanga liphuma lalingabonakali emkhathizwe, umbala kancane a umkhumbi.

Umzamo wokuqala ukuba achaze lokho uthingo senziwe 1611 Antonio Dominisom. incazelo yakhe ayehlukile kuzo iBhayibheli, ngakho enikwa isigwebo sokufa. Ngo 1637, Descartes wanikeza incazelo yesayensi zalesi simo kusekelwe kwalungiswa izinkunga zokubona reflection singakutholi ukukhanya kwelanga. Ngaleso sikhathi, sasingazi mayelana ukunwetshwa ugongolo kulelizinga kungavumela, okungukuthi, ukuhlakazwa. Ngakho-ke, Descartes Kwakuwuthingo emhlophe. Ngemva kweminyaka engu-30 "zaveza 'Newton, kuqhakambisa theory uzakwabo echaza kwalungiswa izinkunga zokubona ray amaKhaladi amathonsi emvula. Naphezu kweqiniso lokuthi imfundiso yokuziphendukela iminyaka engaphezu kuka-300, it is washayelwa kahle, uthingo, Izici eziyinhloko zalo (ilungiselelo izimbali, isikhundla lwesikhathi, izilungiselelo engeli).

Kuyamangalisa ukuthi privychnyye kithi ukukhanya namanzi ndawonye ukudala i, ubuhle entsha ngokuphelele zicatshangwe, omuhle wobuciko, kunikelwe ngayo kwabanye kithi ngokwemvelo. Rainbow uhlale kuqubule imizwelo nangenxa uhlala imemori.
