Obin na lantarki radiation. Features, halaye, da aikace-aikace

Obin na lantarki radiation - shi ne electromagnetic radiation, wanda kunshi wadannan jeri: decimeter, santimita da millimeter. Its zango jeri daga 1 m (mita a wannan harka shi ne 300 MHz) zuwa 1 mm (mita 300 GHz).

Wide m aikace-aikace na obin na lantarki radiation aka samu na da hanyar da ba-lamba dumama jikinsu da kuma abubuwa. A duniyar kimiyya, wannan samu aka yi amfani da baje a cikin bincike na m sarari. Sabõda kuma mafi sanannen domin ta yin amfani - a gida obin na lantarki dafuwa. A manyan masana'antu da shi da ake amfani da zafi magani na karafa.

Har ila yau, to date, da obin na lantarki radiation ya yaɗu a radar. Antennas, karba da kuma riwayar a gaskiya - tsada abubuwa, amma sun samu nasarar biya kashe saboda babbar bayani obin na lantarki sadarwa tashoshi iya aiki. Rating na ta yin amfani a cikin gida da kuma a samar saboda gaskiyar cewa wannan sai} irin radiation ne, sabili da haka, abu ne mai tsanani daga ciki.

Sikelin da electromagnetic mitoci, kuma wajen da farko da kuma ƙarshen, wakiltar biyu jinsin siffofin radiation:

• ionizing (kalaman mita fiye da mita na bayyane haske).
• nonionizing (watsi mita ƙananan fiye da mita na bayyane haske).

Ga wani mutum ya gabatar da wani hadari uncharged superhigh-mita radiation, wanda kai tsaye ya shafi ɗan adam biotoki tare da wani mita na 1 zuwa 35 Hz. Kamar yadda mai mulkin, uncharged obin na lantarki radiation tsokani wanton gajiya, cardiac arrhythmia, tashin zuciya, karu a total jiki sautin kuma mai tsanani da ciwon kai. Irin wannan bayyanar cututtuka ya zama wata alama da cewa yana kusa da tushen cutarwa radiation, wanda zai iya sa muhimmanci lalacewar kiwon lafiya. Duk da haka, da zaran daya ya fita daga hadari zone, malaise ceases da wadannan m bayyanar cututtuka bace a kan nasu.

Kara kuzari watsi da aka bude da baya a 1916, wani m masanin kimiyya Einstein. Wannan sabon abu ne aka bayyana a matsayin shi ne tasiri na waje electromagnetic filayen, tasowa a gwamnatin rikon kwarya a wani electron a zarra daga wani babba makamashi matakin zuwa ƙananan daya. Radiation cewa taso a nan ne ake kira jawo. Ya na da wani sunan - da kara kuzari watsi. Its alama ne cewa zarra fitarda wani electromagnetic kalaman - rabuwa, mita, lokaci, kuma shugabanci na yaduwa ta wannan matsayin cewa na asali kalaman.

Jawo radiation, masana kimiyya sun yi amfani da matsayin tushen ga zamani lasers, wanda, bi da bi, ya taimaka a cikin halittar fundamentally sabon zamani na'urorin - misali, jimla hygrometers haske amplifiers, da dai sauransu ...

Godiya ga Laser, sabon fasaha yankunan - kamar Laser fasaha, holography, kuma maras mike Hadakar kimiyyan gani da hasken wuta, Laser sunadarai. Ana amfani da magani domin hadaddun ayyukan a kan idanu domin tiyata. Jituwar da monochromaticity na Laser sa shi ba makawa a spectroscopy, isotope rabuwa, tsarin aunawa kusurwa velocities da svetolokatsii.

Obin na lantarki radiation - shi ne ma mai rediyo watsi, amma shi yana nufin da infrared iyaka, kuma ma yana da mafi mita a rediyo band. Tare da wannan radiation da muke fuskanta sau da yawa a rana ta amfani da wani obin na lantarki tanda, don dumama abinci, da kuma magana a kan wani wayar hannu. A sosai ban sha'awa da kuma muhimmanci yin amfani da shi, Taurari sun samu. A obin na lantarki radiation da ake amfani da nazarin cosmic bango ko relic radiation lokaci na Big Bang, wanda ya faru biliyoyin shekaru da suka wuce. Astrophysicists nazarin haske na heterogeneity a wasu sassa na sama, yana taimaka wa san yadda duniya kafa taurari.
