Unxibelelwano olungenazingcingo kubomi bemihla ngemihla
Amaza:● Undoqo wonxibelelwano kukusasazwa kolwazi, ubukhulu becala ngohlobo lwamaza. ● Amaza ahlulwe abe ngamaza omatshini, amaza ombane, amaza amaza kunye namaza omxhuzulane (unxibelelwano lwequantum). ● Izilwanyana nezityalo zifunde ukusebenzisa amaza esandi, i-infrared nokukhanya okubonakalayo ngokuphonononga ngendaleko.
amaza ombane:
Okwangoku, i-electromagnetic wave idla ngokusetyenziswa yi-electromagnetic wave, enokwahlulwa ibe ngamacandelo amaninzi ngokubanzi:
● Irediyo (R) (3Hz~300MHz) (iTV, unomathotholo, njalo njalo.)
● I-Microwave (IR) (300MHz~300GHz) (irada, njl.)
● I-Infrared (300GHz~400THz)
● Ukukhanya okubonakalayo (400THz~790THz)
●UV
● X-reyi
● imitha ye-gamma
Isicelo semihla ngemihla:
Iibhendi zihlulwe kwaye zisetyenziselwa iinjongo ezahlukeneyo, ezifana ne-AM, i-FM, usasazo lwe-TV, unxibelelwano lwe-satellite, njl., Ungabhekisela kumaxwebhu asemthethweni amazwe athile.I-GSM, i-3G, kunye ne-4G zonke zii-microwaves.
Iisathelayithi zikwalunxibelelwano lwe-microwave.Awona maza afanelekileyo onxibelelwano ngesathelayithi yi-1-10GHz frequency band, oko kukuthi, ibhendi ye-microwave frequency. Ukuze kuhlangatyezwane neemfuno ezingakumbi nangakumbi, kuye kwafundwa kwaye kwasetyenziswa iibhendi zamaza amatsha, ezifana ne-12GHz, 14GHz, 20GHz kunye ne-30GHz.IHuhutong yiTV yesathelayithi, enikezelwa yiZhongxing 9 satellite.Ngamanye amazwi, ukupakishwa kwale nkqubo yosasazo ephilayo kunamandla ngokwenene, vele uye kwiwebhusayithi esemthethweni ukuze uyibone.Iifowuni zesathelayithi (zohambo kunye neenqanawa) sele zilingana ne-smartphone.IBluetooth kunye ne-wifi zii-microwaves.Izilungisi zomoya, iifeni, kunye nolawulo olukude lweTV olunombala lune-infrared.I-NFC yirediyo (Near Field Communication luhlobo olufutshane, iteknoloji yerediyo yefrikhwensi ephezulu esebenza kwi-13.56MHz kumgama we-20cm).Ithegi zeRFID (iithegi zefrikhwensi ephantsi (125 okanye 134.2 kHz), iithegi zefrikhwensi ephezulu (13.56 MHz), iithegi ze-UHF (868~956 MHz) kunye nethegi zemicrowave (2.45 GHz)
