Radiation ebonakalayo

Mhlawumbi weva ngalo ezizodwa amaza ziqondeka iliso ebantwini, yomxhaso inxalenye ethile spectrum nokuba ngamaza 380 NM (ukuba Violet) ukuya 780 NM (obomvu). Le yemisebe ebonakalayo. Izinto zobumnini Kuqhelekile kuboniswa kule terahertz, sinokufumanisa ngokulinganisa impendulo frequency kwamaza ezinjalo (sifumana kukho umsantsa 400-790 THz). radiation ebonakalayo kwakhona ngokuba ukukhanya okubonakalayo. Ukuze ukubeka ngakumbi nje, kuba ukukhanya apho aqhele ukuba thina, kwaye icala ebonakalayo apho musa nokuba ucinga. Isalathisi kakhulu ezibuthathaka amehlo ethu ukuze 555 NM (le yinxalenye uhlaza spectrum, 540 THz).

Interesting Inyaniso: malumga ayiqulathanga ziqulathe eminye imibala baqonda sithi. Umzekelo, akukho umbala pink (izithunzi ezikhanyayo). Oku kwenziwa xa kuxutywa eminye imibala.

Ngaba wakha wazibuza ukuba kutheni isibhakabhaka ibukeka blue? Yinto elula: yinxalenye spectrum kunye kwamaza emfutshane saa-moya ngaphezu kokuba ubude ehambelana ukuya kwicala ebomvu spectrum. Ngenxa kule isibhakabhaka siluhlaza, ingakumbi emini. radiation Ebonakalayo engena babizwa ngokuba "window optical". Lo mmandla malumga ojikeleze umhlaba abazidubi ukufunxa.

Ezinye izilwanyana babone ukukhanya, bengakwazi ukufikelela kulo mbono yabantu (it nje ayikho kuluhlu obubonakalayo contact). izinambuzane ezininzi (umz, iinyosi) ukuqonda uluhlu yelanga, ngoko ayakhawuleza ukufumana incindi ezimbalini. imitha yelanga kukuba uyakwazi ukubona neentaka zezulu. Ezinye iintlobo zeentaka nokuba neelebhile ezibonakalayo kuphela ngohlobo radiation, apho inkunzi nemazi ukugqiba ngokuchanileyo omnye.

Kubonakele ukusetyenziswa bokukhanya kunye ebantwini. lolona hlobo luqhelekileyo layo - ubushushu ezisekelwe isindululo-athom: umzimba elikhulu itshiswa, kokukhona akhawulezayo intshukumo-athom eziqhuma ukukhanya ingozi. Njengezi thina imithombo ukukhanya - ilanga, igqengezelayo, ikhandlela (nelangatye) - kukho imithombo thermal bokukhanya.

Lo mzekelo ulandelayo - electroluminescence. Apha, amandla ezibangela amadlozi ukukhanya, athom olufunyenwe kwimithombo nonthermal. Xa khupha zombane entsimini yegesi ingxelo energy ethile agciniweyo, electron awuxabele athom (elithi "zingqubane"), kwaye amandla athom yimincili sigcina sele ngokohlobo chweba (electroluminescence).

Electroluminescence ngoku kusetyenziswa iimpawu zentengiso olukhanyayo. Ngendlela, ukuba ezimibalabala Aurora kwakhona ibhekisa yimbonakalo electroluminescence: ebizwayo isisi yi-Sun, uthanda yi lo mhlaba otsalayo iplanethi yethu, yimincili xa nezibonda zayo, kwaye ukukhanya thina. Kodwa wesizalo cathode ray kwi ukukhanya kamabonakude cathodoluminescence ngenxa: ziyavutha apha kubangela electron bombardment.

Chemiluminescence - omnye umzekelo bokukhanya. Apha ngesiphumo ukukhanya uba amandla kukhululwa ekudibaneni kwemichiza. umthombo lobushushu ukukhanya ukuba iqondo lobushushu eliphakathi apho emi kuyo. Umzekelo ukuze akhonze kakuhle nje sinambuzane kunye kancinane yimbonakalo yegolide green "isibane". Ukukhanya kunye nezinye izinto eziphilayo: ethile intlanzi, iintsholongwane kunye nezinambuzane. Ngamanye amaxesha ungabona ukuvutha ezibolayo imithi.

Ezinye yomzimba eqala likhazimle emva kokuba boniswa ukukhanya: okubamba amandla, kuba bona baba imithombo ukukhanya. It - iimpawu photoluminescence apho ezisetyenziswa kakhulu Iipeyinti, impahla, iimpawu zendlela, njalo njalo.

Amacandelo Umbala ukukhanya ebonakalayo kusetyenziswa kulo mkhuba ngengqondo: Green yaziwa ukuba ekuthobeni red - Kubangela, neengubo ezimfusa, emnyama kunye nemisonto - phezu koko, zinqanda de noxinzelelweyo, kunye nokunqongophala umbala omhlophe ebantwini nokudandatheka azenzeki. radiation ebonakalayo kusetyenziswa amayeza (chromotherapy): umzekelo, umbala otyheli isetyenziswa kunyango lwezifo ezithile iliso. ukukhanya elibomvu waphilisa izifo ezithile kunye kwegazi unamadlala ngesondo: infantilism, nenzalo, ukuphazamiseka sexesheni kwabasetyhini, izixa zaneleyo imbewu emadodeni anaphrodisia. ukukhanya Blue ephelisa ukurhawuzelela, imphathe diathesis exudative kunye neentlobo-ntlobo ukopha.
