Yiziphi amagagasi kagesi

Bambalwa abantu bazi ukuthi emisebeni ye kagesi imvelo ogcwele yonke. amagagasi kagesi kuthiwa lokusakaza emkhathini. Kuye ukuvama oscillations ngamagagasi ngesimo division yabo ku ngokukhanya okubonakalayo, umsakazo amaza, infrared, kanye nokunye. Ukuba khona esiwusizo sokuba nezinto eziqondile amagagasi kagesi okuye kungase kutholakale empirically ngo-1880 yi-usosayensi German H. Hertz (ngenhlanhla ngezinga elithile imvamisa ngegama lakhe).

Yiqiniso physics ukuthi yaziwa kazibuthe uhlobo olukhethekile ndaba. Naphezu kweqiniso lokuthi iso bangabona kuphela ingxenye encane yawo, umphumela wawo kulomhlaba nawo njengomnyango mkhulu kakhulu. amagagasi kagesi kukhona esiphelweni emkhathini zithwala ezilandelanayo uxhumana kazibuthe kanye kagesi. Nokho, igama elithi "ukusabalala" kulokhu akuyona ngempela lesifanele: kuba, kunalokho, perturbation wave-like isikhala. Isizathu yokwenza i wave kagesi Akukhona ukubukeka emkhathini nge ekushintsheni ensimini kagesi ngokuhamba kwesikhathi. Njengoba yaziwa, kukhona okusobala phakathi emasimini kagesi kazibuthe. Engingakusho nje kokukhumbula umthetho ukuthi emhlabeni yimuphi umqhubi ne kazibuthe lwamanje samanje. I kuyizinhlayiyana, okuyizinto amagagasi kagesi, iqala siyekethise, futhi uma kukhona ukunyakaza, ngakho kukhona emisebeni amandla. Inkambu kagesi nge ngejubane lokukhanya sidlulile eduze le kuyizinhlayiyana lapho esephumule, okuholela emkhakheni kagesi imvelo esisha esenziwe. Futhi njengoba Amasimu esihlobene, ulandele kazibuthe. Inqubo ubabonisa ngendathane. Kulokhu, ukunyakaza wangempela, kodwa kukhona kuyizinhlayiyana iyehla iyenyuka.

On the kungenzeka ukusetshenziswa esiwusizo sokuba nezinto eziqondile lolu hlobo yemvelo ka oscillations wacabanga isikhathi eside. Ezweni lanamuhla amandla amagagasi kagesi is kabanzi ngakho wasebenzisa ukuthi abantu abaningi angaluboni, ukuthatha kalula. Isibonelo esimangalisayo - amaza omsakazo, ngaphandle ngalo ebandleni bekungekhe kukghonakale ku namathelevishini nomakhalekhukhwini.

Le nqubo kanje: umqhubi metal ilolongwe ngokukhethekile (antenna) njalo ngocansi modulated iselulo segama lefayela. Ngenxa izakhiwo kagesi emhlabeni umqhubi kagesi kwenzeka, bese kazibuthe, okuholela ekushayweni amagagasi kagesi Kwenziwa. Njengoba le oscillation imvamisa okungukuthi modulated, bona sife othile oda, Coded ulwazi. Ukuze abambe imvamisa oyifunayo, umamukeli ethola antenna iqoqo design akhethekile. It ikuvumela ukuba ukhethe kusuka ingqikithi kagesi ngemuva imvamisa oyifunayo. Uma ku owamukelayo metal, igagasi kancane ibe kagesi lamanje umthombo kwezwi. Babe ufike esikhumulweni inzuzo iyunithi nokulawula ukusebenza kwe-idivayisi (hambisa isipika Isigaxa, baphendukela le electrode TV izikrini).

Lamanje kwaphumela kusukela kagesi amagagasi kungenziwa kalula ukubonwa. Ubufakazi obanelisayo angenalutho ikhebula umqhubi esukela antenna kuya umamukeli, uthinte isisindo ingqikithi (radiators, loop phansi). Kuleli qophelo, phakathi phansi futhi inhlansi eziphilayo kuzuba - lena ibonakalisa zamanje eyenziwe lukamakhalekhukhwini. Inani layo mkhulu, Transmitter eduze futhi ibe namandla ngokwengeziwe. Futhi kakhulu ehlaselwe ukucushwa kwe-antenna.

Enye yezindlela uJehova alubonisa ngayo amagagasi kagesi, okuyinto eziningi ezibhekana nazo nsuku zonke ekhaya - ukusetshenziswa microwave oven. Izungezisa umugqa ensimini ukuwela kuncike futhi uthumele abanye amandla abo ngokubeka amalahle.
