Band Frequency - si ballaaran loo isticmaalo qalab casri ah oo alaabta

Superhigh kala duwan oo soo noq - waa shucaaca electromagnetic, taas oo ah in kala duwan oo u dhexeeya ee hirka sare iyo mawjadaha TV fog infrared. In dalalka Ingiriiska ku hadla waxaa lagu magacaabaa kala duwan microwave sababtoo ah Milanello waa mid aad u yar marka la barbardhigo ruxruxo raadiyaha. oscillations Kuwanu waa dhexe dhexeeya shucaaca iftiinka iyo qaybaha kala radio caadiga ah, si kastaba ha ahaatee, waxay leeyihiin isku mar sifooyinka hirarka iftiinka iyo radio. Iyo sidoo kale shucaac kaamerada, ay qaybiyey qaab dogob, iyo ka muuqataa. Caadiga ah ee hirarka sida iyo faafinta ee xariiq toosan, oo xirmi oo dhan shay adag. Sidaa darteed, dad badan oo radar antenna - waa in la kordhiyo xubno indhaha ee foomka of muraayadaha waaweyn ama lenses.

Waa in la ogaadaa in kala duwan oo inta jeer ee ay la mid tahay ku shucaaca dhinacyo warbaahinta iyo, sida, in la ahbaa doonaa by hababka la mid ah. shucaaca microwave ka kooban yahay aragtida ah classical ee hirarka raadiyaha, sidaas darteed si guul leh loo isticmaalo iyada oo loo adeegsanayo isgaarsiinta. Si kastaba ha ahaatee, waxaa aad u muhiim ah in uu leeyahay inta jeer sare iyo sidaas ku heli kartaa fursado badan ee suuqa kala iibsiga ee macluumaadka - waxaa ku caawinaysa in ay hagaajiso waxqabadka isgaadhsiinta. isku mid ah oo warshadu hawada iftiin ka caawisaa in ay noqon waxtar u leh radar iyo codsiyada kale ee technology.

band frequency waxaa sidoo kale loo isticmaalaa in isgaarsiinta satellite ay u gudbiyaan ama macluumaad in ka badan masaafo dheer. Iyada oo la adeegsanayo qalabka elektarooniga ah ee gaarka ah waxaa maqalka iyo retransmitted signal microwave in loo kala qaado by saldhigyada dhulka. The saldhig ugu horeysay sida muuqday 60meeyadii ee qarnigii la soo dhaafay, marka la caawimaaddooda dhigay baahin warbaahinta TV.

Iyada oo ku saleysan waayo-aragnimo ee la soo dhaafay, wax soo saarka satalayt gaar ah xiriir Intercontinental lagu soosaaray. Waqtigan xaadirka ah, kala duwan oo soo noq ultrahigh sida caawisaa malaayiin dad ah si ay u daawadaan kun oo channels heer tayo sare leh. Sidoo kale waxa loo isticmaali karaa si ay u gudbiyaan taleefanka, telefishanka, calaamadaha fax iyo xogta digital.

In dunida maanta ee kala duwan oo soo noq aalladda sare - daaweyn kulaylka ka mid ah cuntooyinka guriga iyo dhirta cuntada-. tamarta ah in ahbaa by laambadihii awood gaar ah, ku urursan Waxaan ahay in mugga yar, oo sidaas jiro daaweynta kulaylka oo cunto ah. Thanks to kuwaas oo rays microwaves iyo foornooyinkaaga dhexdooda microwave aamusnaan shaqeeyaan, ay yihiin is haysta oo nadiif ah. aaladaha noocan oo kale ah ayaa si guul leh loo isticmaalo jikada in diyaarada, ee w / d baabuurta, maqaayado iyo mashiinada lagu iibiyo jidadka, halkaas oo aad u baahan tahay in si deg deg ah u diyaariso cuntada qaar ka mid ah.

Waa in la ogaadaa in ay kaalin weyn ku leh daraasaddan oo ka mid ah guryaha elektarooniga ah ee adkaha ah ee kala duwan waxaa lagu ciyaaray shucaaca microwave. kala duwan oo ah berrinka magnetic ka caawisaa in ay electrons free isku shaandheyn in diyaarad taas oo dadab iyo in ay jihada duurka magnetic. Intaa waxaa dheer, haddii jidhkaaga oo adag in uu hago shucaaca ee microwave ka, ka dibna waxaa si xoogan u nuugo. Tani waxay ifafaale - resonance cyclotron ah, iyo waxa loo isticmaali karaa in lagu cabiro ku ool ah mass of electron ah. Iyada oo la adeegsanayo cabbirka sida, saynisyahano heshay macluumaad badan oo qiimo leh oo ku saabsan semiconductors iyo guryaha elektarooniga ah, iyo sidoo kale biraha iyo metalloid.
