Walaʻauʻana waiwai o nä hawewe electromagnetic

I ka makahiki 1865, ka mea kaulana English physicist John. Maxwell, ma muli o ka hopena o ka hana ma luna o ke ao o Faraday ka electromagnetic a ke kahua, hiki theoretically ho'āpono aku i ka manawa kūpono o ka ola o ka mahinaʻai i loko o ka wa e kaawale aku o kona au, a 'āhewa' ana, i ko lakou ole. Ke kahua hoʻonohonohoʻia ka kumu o ka nalu. Ma o ka waiwai o nä hawewe electromagnetic i ole e nana hiki hoihoi 'mea: ka propagation māmā holo hilinaʻi nui ma luna o ke kaiapuni. No ka laʻana, i loko o ka holo, ia mea ma kahi o 300 tausani. Km / s. No keia nui hoʻopili like i ka mämä holo o ka malamalama, e mea hiki ke Maxwell kuhi i ka malamalama o keʻano o nä hawewe electromagnetic. Kēia i hope hoopaaia ma ka ho okolohua o Hertz. Ma mua o ka Hekikai o Maxwell ka kumumanaʻo i manaoio aku i ka mea i nanaia kukui, X-kukuna, ultraviolet, Radio ka mea,ʻaʻole e pili pū ana pāhawewe. I mea, o ka waiwai o nä hawewe hilinaʻi ma luna o lākou lōʻihi. Ka a pau huahelu o conventionally ua mahele ia i wahi, kela mea keia mea o ka i ua wehewehe aku ma kona hoike ana.

Nā waiwai o ka electromagnetic a ale i kū hoʻokahi no ka mea, o ko lākou AaOIeIOUIeXAOAaIN me ka hoʻomaopopo like waiwai ua wehewehe ia e mau eiiiiiaiou - pila nui a me kaʻume mākenēki. Ke'ī mai, ma o ka hawewe electromagnetic, i mea ole mawaho keiki, nā mahinaʻai lauwili i loko o ko lākou mauʻaoʻao a me Kekoa i mea p ÷ haku i ka olelo o ka propagation o ka nalu. Walaʻauʻana waiwai o nä hawewe electromagnetic i kekahi i kekahi iiiaanoaa o ka hōʻike 'ana, ka nānā' ana i ke 'ano o ke kumu. E noonoo i kekahi o ia mau mea. Nui hou kupono o ia ho i maoli-ao ka hoao ana, no laila, mentally mākou hoʻohana mau manao maalea - Hoʻi Hou nalu mīkini hana wāwahie o directional pāhawewe a me ka pa alima. E like me ua oleloia, o ka hopena i pili i nā mea a pau ano o ka nalu. Ike i ka waiwai o nä hawewe electromagnetic i hiki ke manipulated i loko o ka makemake ano.

I ka maʻamau o ke ola, kela mea keia mea o mākou uaʻalo me ka kela la noʻonoʻo. No ka laʻana, i kekahi manawa, a hiki i ka lawe lima kelepona nalowale hui 'ana me ka waihona ipu noaioee, e hele i loko o ka lumi me ka manoanoa pōhaku puna pā pōhaku, a me ke ahiahi, i loko o ka maʻamau hale'eleweka. Hoi mai i ka hoʻokolohua, ina ka lēkio leo a me ka pa alima hoʻonoho ma ka huina i kekahi i kekahi, alaila, i ka hoailona e ole e 'akomi i (emitter directional). Akā, he mea pono e waiho i ke kuʻina o kaʻike mau laina elua (ao ao maʻi lele) o ka metala papa, i ka pa alima e hopu i ka malamalama,ʻo ia hoʻi, he mea i ka manaʻo. Similar waiwai o nä hawewe electromagnetic ua kālaiʻia i loko o ka olelo o ka like o ka pana pua o ka mea hiki wale mai a me ka noʻonoʻo.

Na kēia waiwai - ka mea, ua refracted. A hiki i ka pa alima ka wahi a me ka directional kumu ma kekahi mau wahi kiekie, i ka hoailona e ole e hopu. Akā, inā ma waena o ia e waiho i ka paraffin kupa, ka mea a pau noaia hana. Kēia mea ma muli o ia i kekahi loli ma ke ala e hiki aku o ka propagation o nä hawewe ma ka palena ma waena o nā dielectric Media, (makani a me ka paraffin).

Eia, ka mea, o ke kumukuai i olelo ia i ke 'ākeʻakeʻa. Inā ka metala papa elua ka hooponopono ia i loko o ka wahi koke o kekahi i kekahi, ho okumu i ka huina iki uuku ma mua o 180, alaila, i ka pāhawewe Radio nalu ma luna o ka pa alima pepa, e hopu i ka unuhi i loko o pinepine 'ke kaumaha ma muli kona wahi e pili ana i ka a lahilahi. A maikaʻi-ike laʻana - ka ukali pa, oia no. He ka "papa" amplifies ka hōʻailona, kaʻohiʻana i ka hele liʻiliʻi nalu a me ka i kiaʻia ia mau mea ma luna o ka pa alima.

Kekahi luawai-ike hiʻona - diffraction. I ka hapa, no ka mea, no ka mea, hooponopono iho i ke hoʻohana i nā radios. 'Ike i nā kēia: ma waena o ka mīkini hana wāwahie, a me ka pa alima i ka mea hiki ke hooheheeia papa, kahi o ka mamao ma waena o ia - palena iki. E like me ka hopena, i hoailona, e like me ka lewa mai ka una honua hoʻi, a me kaʻaoʻao mīkini hana wāwahie. Akā, inā ua pālahalaha aʻe ma kaʻaoʻao o ka una honua lēkio leo a me ka pa alima, ka neaiae ma ka papakaumaka. Kēia hana a puni nā pilikia aie i ka waiwai o ka nalu.
