I-eriyali ekwaziyo ukuthumela okanye ukufumana amaza e-electromagnetic (EM).Imizekelo yala maza ombane wombane abandakanya ukukhanya okuvela elangeni, kunye namaza afunyenwe yiselfowuni yakho.Amehlo akho afumana ii-eriyali ezibona amaza e-electromagnetic frequency ethile."Ubona imibala (ibomvu, eluhlaza, eluhlaza okwesibhakabhaka) kwizansi ngalinye. Ubomvu kunye nobhlowu zizihlandlo ezahlukeneyo zamaza anokubona amehlo akho.
Onke amaza ombane asasaza emoyeni okanye emkhathini ngesantya esifanayo.Esi santya simalunga ne-671 yezigidi zeerandi ngeyure (i-1 billion yeekhilomitha ngeyure).Esi santya sibizwa ngokuba sisantya sokukhanya.Esi santya simalunga nesigidi ngokukhawuleza kunesantya samaza esandi.Isantya sokukhanya siya kubhalwa kwi-equation ka-"C".Siza kumeta ubude bexesha ngeemitha, ngemizuzwana, nangeekhilogram.Iiequations zexesha elizayo kufuneka sizikhumbule.
Ngaphambi kokuba sichaze amaxesha amaninzi, kufuneka sichaze ukuba yintoni amaza ombane.Le yintsimi yombane esasazeka kude nomthombo othile (i-antenna, ilanga, inqaba yomsakazo, nantoni na).Ukuhamba kwindawo yombane kunomhlaba wemagnethi onxulumene nawo.Ezi ndawo zimbini zenza i-electromagnetic wave.
Indalo iphela ivumela la maza ukuba athabathe nayiphi na imilo.Kodwa eyona milo ibalulekileyo yi-sine wave.Oku kucwangciswe kuMfanekiso 1. Amaza ombane ayahluka ngendawo kunye nexesha.Utshintsho lwendawo luboniswe kuMzobo 1. Utshintsho kwixesha luboniswe kuMfanekiso 2.
Umfanekiso 1. I-Sine wave ecwangciswe njengomsebenzi wesikhundla.
Umfanekiso 2. Yila i-sine wave njengomsebenzi wexesha.
Amaza ngamaxesha athile.Iliza liphinda kanye kwisekondi nganye kwimilo ethi "T".Icwangciswe njengomsebenzi esithubeni, inani leemitha emva kophindaphindo lwamaza linikiwe apha:
Oku kubizwa ngokuba yi-wavelength.I-Frequency (ebhalwayo "F") linani nje lemijikelo epheleleyo egqitywe ngamaza ngesekhondi enye (umjikelo weminyaka engamakhulu amabini ubonwa njengomsebenzi wexesha elibhalwe 200 Hz okanye 200 "hertz" ngomzuzwana).Ngokwezibalo, le yifomula ebhalwe ngezantsi.
Ukuba umntu uhamba ngokukhawuleza kangakanani kuxhomekeke kubungakanani benyathelo lakhe (ubude bobude) buphindaphindwe ngomlinganiselo wabo wamanyathelo (ukuphindaphinda).Ukuhamba kwamaza kuyafana ngesantya.Ukukhawuleza kangakanani amaza oscillates ("F") aphindaphindwe ngobungakanani bamanyathelo amaza awathathayo kwixesha ngalinye ( ) inika isantya.Le fomula ilandelayo kufuneka ikhunjulwe:
Ukushwankathela, i-frequency ngumlinganiselo wokuba i-wave oscillate ikhawuleza kangakanani.Onke amaza ombane ahamba ngesantya esifanayo.Ke ngoko, ukuba i-electromagnetic wave ijika ngokukhawuleza kuneliza, iliza elikhawulezayo kufuneka libe nobude obufutshane.Ubude bexesha elide buthetha ukuphindaphinda okuphantsi.
