Izakhiwo eziyisisekelo amagagasi kagesi

Ngo-1865, lo odumile physics IsiZulu John. UMaxwell, ngokusekelwe imiphumela umsebenzi ekutadisheni Faraday sika ensimini kagesi, ungase kwakuthiwa bathethelele kungenzeka abe khona emasimini anjalo, singekho imisinga kanye nezimali ezibizwayo, zohlobo yabo. Ukulungiselelwa inkambu yomthombo igagasi. Ngokufunda izakhiwo amagagasi kagesi ukuthi ngeke zinganakwa iqiniso elithakazelisayo: the velocity esiphelweni kuncike imvelo. Ngokwesibonelo, ngo-a cleaner, kumayelana ayizinkulungwane 300. Km / s. Njengoba lesi silinganiso oluhambisana ngejubane lokukhanya, kungenzeka ukuba uMaxwell ngokuthi ukukhanya kuhamba njengamaza uhlobo amagagasi kagesi. Kamuva kuqinisekiswa ucwaningo Hertz. Ngaphambi kokufika theory uMaxwell sika kukholakala ukuthi ukukhanya ebonakalayo, X-ray, oku-ultraviolet, umsakazo kungukuthi ezihlobene emisebe. Eqinisweni, property amagagasi incike ubude bawo. Lonke uhla evamile ihlukaniswe izifunda, ngasinye sazo libhekene zako.

I izakhiwo amagagasi kagesi ahlukile ngenxa yokusebenza zabo into evamile alichaza izingxenye ezimbili - kagesi kazibuthe. Ngakho, ngo-wave kagesi, okuyinto azinalo ithonya zangaphandle, zombili izinkambu ziyehluka iziqondiso zabo futhi izindiza okuyizinto perpendicular isiqondiso Lokusakaza wave. izakhiwo Basic amagagasi kagesi presents sebuningini ubonisa, kungakhathaliseki uhlobo umthombo. Ake ucabangele ezinye zazo. zibelula ukumela nakho bomhlaba wangempela, ngakho ngokwengqondo sisebenzisa amadivayisi amabili - amagagasi generator emisebeni ohlangothini kanye umamukeli. Njengoba sekushiwo, imiphumela ziyasetshenziswa zonke izinhlobo amagagasi. Ukwazi property amagagasi kagesi okungatholakala ukusetshenziswa ngendlela oyifunayo.

Ekuphileni kwethu kwansuku zonke, ngamunye wethu ubhekene reflection nsuku zonke. Ngokwesibonelo, ngezinye izikhathi, ukuba ifoni ephathekayo badukelana esiteshini base, vele uye ekamelweni izindonga awugqinsi ukhonkolo, noma ngisho ezejwayelekile endlini ikheshi. Ukubuyela ekuhlolweni, uma Transmitter kanye umamukeli kahle engela each nye ngalesosikhathi isiginali ngeke ukutholwa (emitter ohlangothini). Kodwa kubalulekile ukubeka ezimpambanweni zomgwaqo imigqa emibili ezivamile (isiqondiso vector) we ipuleti metal, owamukelayo kuyobazuma ukukhanya, okungukuthi, lapho kuveza. izakhiwo Okufanayo amagagasi kagesi washayelwa i kusho nokulingana engeli we kwesifo nekucabangisisa.

Impahla ezilandelayo - it is refracted. Lapho indawo owamukelayo sika futhi umthombo ohlangothini at eziphakeme ezahlukene, isiginali ngeke babanjwe. Kodwa uma phakathi kwabo ukubeka cube upharafini, lonke uhlelo lusebenza. Lokhu kungenxa ushintsho isiqondiso esiphelweni ngamagagasi emngceleni ophakathi abezindaba ezimbili Kwe-dielectric Heating (emoyeni futhi upharafini).

Ngaphezu kwalokho, kuyazuzisa kokukhuluma ukuphazamiseka. Uma amapuleti amabili metal ahlelwe eduze ngokushesha nomunye, ukwakha engela kancane degrees ezincane kuno-180, bese emisebeni amagagasi eshidini umamukeli angeke ukubamba umehluko umfutho kuye indawo yayo ehlobene amashidi. Isibonelo owaziwa - le-satellite dish. Kufana 'ipuleti "icacisa isignali, uqoqa wave ehlakazekele sokugxila kubo phezu umamukeli.

Esinye isici owaziwa - umumo womsebenzi. Ngokwengxenye, lokhu kubangelwa ngakho uphatha ukusebenzisa imisakazo. Yazi lokhu okulandelayo: phakathi generator owamukelayo wafaka ungcwecwe metal, lapho ibanga elibahlukanisile - ubuncane. Ngenxa yalokho, akunasiginali, njengoba kubonakala kusukela ipuleti emuva, ngohlangothi generator. Kodwa uma ukusakaza ezinhlangothini Transmitter ipuleti futhi isamukeli, isiginali uboniswa. Lokhu kwenzeka emhlabeni izithiyo ngenxa impahla amagagasi.
