Shucaaca la arki karo

Waxaa laga yaabaa in aad maqashay gaarka ah hirarka electromagnetic gartay by isha aadanaha, degan qayb ka mid ah qaybaha iyo isagoo Milanello ka mid ah 380 nm (waayo, buluug) in 780 nm (waayo, red). Tani waa shucaaca la arki karo. Guryaha waxaa sida caadiga ah lagu muujiyay terahertz ah, waxaan ka heli kartaa by qiyaaso jawaabta soo noqnoqoshada hirar sida (waxaan u hesho farqi in 400-790 THz ah) ah. shucaaca la arki karo waxaa kaloo loo yaqaan iftiin arki karo. Si aad u badan si fudud ku riday, waa iftiin in ay taas oo aanu aad u bartayba, iyo dhinaca jirka ah oo xitaa ma qabaa. The tilmaame ugu xasaasi ah indhahayaga in 555 nm (oo qayb ka this cagaaran ee spectrum ah, 540 THz).

Dhab ahaantii Interesting: in spectrum ah kuma jiraan qaar ka mid ah midabo ay arkeen noo by. Tusaale ahaan, waxaa jira midab lahayn pink (oo midabo). Waxaa la sameeyey marka la isku daro midabyo kale.

Weligaa mala yaabtay sababta samada u muuqataa buluug ah? Waa wax iska fudud: qayb ka mid ah qaybaha la Milanello gaaban way kala firidhsan by hawada ka badan dherer u dhiganta kooxda cas ee spectrum ah. Sababo la this, cirku waa buluug ah, gaar ahaan hadhkii. shucaaca Muuqata gala ee loo yaqaan "window indhaha ah". Tani gobolka ee spectrum jawiga dhulka ee ma nuugo.

xayawaanka qaar ka mid ah ka arki kartaa iftiin, geli karin aragtida aadanaha (waxay si fudud ma aha in kala duwan ee la arki karo ee xidhiidhka). cayayaanka badan (tusaale ahaan, bees) Arkaa kala duwan ultraviolet ah, waxayna si degdeg ah u heli nectar ee ubaxa. shucaaca waa inay awoodaan si ay u arkaan iyo shimbiraha. noocyada qaar ka mid ah shimbiraha xitaa leeyihiin sumadaha in ay yihiin la arki karo oo kaliya ee foomka of shucaaca, taas oo lab iyo dhaddig si sax ah loo ogaado mid kasta oo kale.

Waxaa laga helay isticmaalka iftiinka la arki karo iyo in aadanuhu. Its ugu badan ee foomka - kulaylka ku salaysan mooshinka ee atamka: jidhka weyn waa kuleelka, si degdeg ah dhaqdhaqaaqa atamka oo dhaadheer iftiin dul dhaceen. All yaqaan in ay na ilo iftiin - qorraxda, incandescent, shumac (olol) - ilo kaamerada iftiinka arki karo.

Tusaalaha soo socda - electroluminescence. Halkan, tamarta taas oo keeni warshadu hawada iftiin, atamka ka ilo nonthermal helay. Marka siideeyn korontada duurka gaaska lagu sheegay a tamarta ogeed qaarkood, electrons ku dhufan atamka ka (ereyga "isku"), iyo tamarta ee atamka ugu faraxsanahay aynu hore u dhawrtaan in qaab luminescence (electroluminescence).

Electroluminescence waxaa hadda loo isticmaalaa calaamadaha advertising ciinwaanka. By habka, Borealis aurora ah ayaa sidoo kale waxaa loola jeedaa in muuqaalka kore ee electroluminescence: eedeeyay qayb ka timaada by Sun, waxaa soo jiitay by duurka ku magnetic of dhulkeenna, waxaan ku faraxsanahay at ulaheedii, iyo iftiinka. Laakiin tuubooyinka ray cathode in uu yahey television cathodoluminescence sabab: halkan iska Ifto sababa duqeymo electron.

Chemiluminescence - tusaale kale oo iftiin arki karo. Halkan natiijada siyasad noqdo tamarta sii daayay falgalka kiimikada. heerkulka il nuur yahay heerkul ah oo dhexdhexaad ah, taas oo waxa uu ku yaalaa. Tusaale ahaan si fiican ugu adeegaan sida firefly a yar dhuxul cagaaran "toosh". Light oo kale noolaha: kalluunka qaar ka mid ah, bakteeriyada iyo cayayaanka. Mararka qaarkood waxaad ku arki kartaa siyasad ee qurmay oo geedo.

Qaar ka mid ah jirka oo ay bilaabaan inay iska Ifto ka dib markii la ileys: dhuuqin tamarta, waxay laftigooda waxa ay noqdeen ilo iftiinka. Waxaa - guryaha photoluminescence ah kuwaas oo si ballaaran loo isticmaalo in rinjiga, dhar, calaamadaha waddooyinka iyo si bixi.

Qaybaha The midabka iftiinka arki karo waxaa loo isticmaalaa in dhaqanka ee cilmi nafsiga: Green loo yaqaan oo dejiyo cas - yididiila galin, iyo guduud, madow iyo buluug - on lid ku ah, joogsada, oo xataa wuxuu dulmay, iyo yaraanta midabka cad in dadka iyo murugada dhacdo. shucaaca la arki karo waxaa loo isticmaalaa in daawada (chromotherapy): tusaale ahaan, iftiinka jaalaha ah waxa loo isticmaalaa in lagu daaweeyo cudurrada indhaha qaarkood. iftiinka Red daawayn cudurada qaar iyo cudurada ku dhaca qanjidhada galmada: infantilism, dhalmo la'aan, xanuunada caadada dumarka, tiro ku filan oo ah farcankii ragga anaphrodisia. iftiinka Blue tiraa cuncun, daweeyo diathesis exudative iyo noocyada kala duwan ee dhiig.
