I-antenna ekwazi ukudlulisa noma ukuthola amagagasi kagesi kagesi (EM).Izibonelo zala maza kagesi zibandakanya ukukhanya okuvela elangeni, namagagasi atholwe umakhalekhukhwini wakho.Amehlo akho athola izimpondo ezithola amagagasi kagesi ngefrikhwensi ethile."Ubona imibala (obomvu, oluhlaza okotshani, oluhlaza okwesibhakabhaka) kugagasi ngalinye. Okubomvu nokuluhlaza okwesibhakabhaka amaza ahlukene nje amagagasi angawazwa amehlo akho.
Wonke amaza kagesi azibuthe asakazeka emoyeni noma emkhathini ngesivinini esifanayo.Leli jubane lilinganiselwa ku-$671 million ngehora (1 billion amakhilomitha ngehora).Lesi sivinini sibizwa ngesivinini sokukhanya.Lesi sivinini sishesha ngokuphindwe izikhathi eziyisigidi kunejubane lamagagasi omsindo.Isivinini sokukhanya sizobhalwa ku-equation ethi "C".Sizokala ubude besikhathi ngamamitha, ngamasekhondi, namakhilogremu.Izibalo zesikhathi esizayo kufanele sizikhumbule.
Ngaphambi kokuchaza imvamisa, kufanele sichaze ukuthi ayini amagagasi kagesi.Lena inkambu kagesi esabalele kude nomthombo othile (i-antenna, ilanga, umbhoshongo womsakazo, noma yini).Ukuhamba endaweni kagesi kunenkambu kazibuthe ehlotshaniswa nayo.Lezi zinkambu ezimbili zakha i-electromagnetic wave.
Umkhathi uvumela la magagasi ukuthi enze noma isiphi isimo.Kodwa umumo obaluleke kakhulu yi-sine wave.Lokhu kuhlelwe kuMfanekiso 1. Amagagasi kagesi ayahlukahluka ngendawo nesikhathi.Izinguquko zendawo ziboniswa kuMfanekiso 1. Izinguquko zesikhathi ziboniswa kuMfanekiso 2.
umfanekiso 1. Igagasi lesine elakhiwe njengomsebenzi wesikhundla.
umfanekiso 2. Hlela igagasi elinesine njengomsebenzi wesikhathi.
Amagagasi ahamba ngezikhathi ezithile.Igagasi liphinda kanye njalo ngomzuzwana ngesimo sika-"T".Ihlelwe njengomsebenzi esikhaleni, inani lamamitha ngemva kokuphindaphinda kwegagasi linikezwa lapha:
Lokhu kubizwa ngokuthi i-wavelength.Imvamisa (ebhalwe ngokuthi "F") imane iyinani lemijikelezo ephelele igagasi eliyiqeda ngomzuzwana owodwa (umjikelezo weminyaka engamakhulu amabili ubonwa njengomsebenzi wesikhathi obhalwe ukuthi 200 Hz noma 200 "hertz" ngomzuzwana).Ngokwezibalo, lena ifomula ebhalwe ngezansi.
Ukuthi umuntu uhamba ngokushesha kangakanani kuncike kusayizi wesinyathelo sakhe (ubude begagasi) obuphindwe ngezinga labo lezinyathelo (imvamisa).Ukuhamba kwamagagasi kuyefana ngesivinini.I-wave oscillates ("F") ishesha kangakanani iphindwe ngosayizi wezinyathelo ezithathwa yigagasi isikhathi ngasinye ( ) linikeza isivinini.Ifomula elandelayo kufanele ikhunjulwe:
Ukufingqa, imvamisa isilinganiso sokuthi igagasi lizungeza ngokushesha kangakanani.Wonke amaza kagesi ahamba ngesivinini esifanayo.Ngakho-ke, uma igagasi kazibuthe lizungeza ngokushesha kunegagasi, igagasi elisheshayo kufanele futhi libe nobude obufushane.Ubude begagasi ende busho imvamisa ephansi.
