Fesootaiga uaealesi i le olaga i aso faisoo  

Galu:● O le ute o fesoʻotaʻiga o le tuʻuina atu o faʻamatalaga, aemaise lava i foliga o galu.  ● O galu ua vaevaeina i galu faʻainisinia, galu electromagnetic, galu o mea ma galu o le kalave (comantum communication).  ● O manu ma laau na aʻoaʻoina le faʻaogaina o galu leo, infrared ma le malamalama vaʻaia e ala i suʻesuʻega evolusione.

galu electromagnetic:

I le taimi nei, o le galu electromagnetic e masani ona faʻaaogaina o le galu electromagnetic, lea e mafai ona vaevaeina i ni vaega lautele:

●Leitio (R) (3Hz~300MHz) (TV, leitio, ma isi)

●Microwave (IR) (300MHz~300GHz) (radar, ma isi)

●Infrared (300GHz~400THz)

●Malamalama vaaia (400THz~790THz)

●UV

●X-ray

● gamma ave

Talosaga i Aso Ta'itasi:

  O fusi e vaevaeina ma faʻaaogaina mo faʻamoemoega eseese, e pei ole AM, FM, faʻasalalauga TV, fesoʻotaʻiga satelite, ma isi, e mafai ona e vaʻai i pepa aloaia a atunuu patino.GSM, 3G, ma le 4G o microwave uma.

Satelite foi o fesootaiga i microwave.Ole ala e sili ona talafeagai mo feso'ota'iga satelite ole 1-10GHz fa'alava fa'alava, o lona uiga, ole fa'alava ole microwave.  Ina ia fa'amalieina le tele ma le tele o mana'oga, ua su'esu'eina ma fa'aogaina laina fou, pei ole 12GHz, 14GHz, 20GHz ma le 30GHz.Huhutong o le satelite TV, tautuaina e Zhongxing 9 satelite.I se isi faaupuga, o le afifiina o lenei faʻasalalauga faʻasalalauga e matua mamana, na o le alu i le upega tafaʻilagi aloaia e vaʻai ai.Telefoni satelite (mo malaga ma va'a) ua pei o se telefoni.O le Bluetooth ma le WiFi o microwaves.Ea malulu, ili, ma fa'asolo mamao TV lanu e infrared.O le NFC o le leitio (Near Field Communication o se tekinolosi faʻasalalau puʻupuʻu, maualuga maualuga e faʻaogaina i le 13.56MHz i le mamao e 20cm).Fa'ailoga RFID (fa'ailoga maualalo (125 po'o le 134.2 kHz), fa'ailoga maualuga (13.56 MHz), fa'ailoga UHF (868~956 MHz) ma fa'ailoga microwave (2.45 GHz))
