Emisebeni ebonakalayo

Mhlawumbe nawe wake wezwa mayelana ekhethekile amagagasi kagesi ziqondakala Iso lomuntu, bangazihluphi ingxenye ethile bohlu nokuba nombono ka 380 nm (i-violet) ukuze 780 nm (obomvu). Lona emisebeni ebonakalayo. Izakhiwo ke ngokuvamile kuboniswe terahertz, singathola ngu yokulinganisa impendulo imvamisa amagagasi anjalo (sithola igebe 400-790 THz). emisebeni Kubonakala ubizwa nangokuthi ukukhanya ebonakalayo. Ukuyibeka kalula, kuba ukukhanya thina bajwayele ngakho, futhi ohlangothini ngokomzimba zazo musa noma ucabange. Inkomba sizwele kwamehlo ethu kuya 555 nm (le ngxenye oluhlaza bohlu, 540 THz).

Eqinisweni ezithakazelisayo: e bohlu ayiqukethe ezinye imibala ziqondakala kithi. Ngokwesibonelo, akukho umbala pink (kanye shades). Kumiswa It is ngesikhathi ukuxuba eminye imibala.

Ingabe wake wazibuza ukuthi kungani esibhakabhakeni ubukeka eluhlaza? Kulula: ingxenye spectrum nge wavelength iDemo asakazeke ngendiza ngaphezu obuphelele elihambisana ohlangothini obomvu bohlu. Ngenxa yalesi isibhakabhaka siluhlaza, ikakhulukazi emini bebade. + emisebeni Kubonakala engena okuthiwa "ifasitela optical". Le ndawo bohlu ozungeze umhlaba ayikwazi ukudonsa.

Ezinye izilwane ungabona ukukhanya, zingakwazi ukufunda umbono womuntu (kuvele alikho ibanga ebonakalayo oxhumana naye). Izinambuzane eziningi (isib, izinyosi) ukuqonda ububanzi ultraviolet, ngakho bayashesha ukuthola umpe ezimbalini. emisebeni ultraviolet kuyinto akwazi ukubona nezinyoni. Ezinye izinhlobo zezinyoni ngisho namalebula ebonakalayo kuphela ngesimo emisebeni, lapho owesilisa nowesifazane ukunquma ngokunembile nomunye.

Ucwaningo luthole ukusetshenziswa ukukhanya ebonakalayo futhi abantu. ezivame kakhulu injalo - ukushisa esekelwe ukunyakaza kwama-atom: umzimba emikhulu uyabaselwa, ngokushesha lo ukunyakaza kwama-atom okuyinto ihlaba umkhosi ukukhanya phezu ukushayisana. Zonke ajwayelekile kithi imithombo ukukhanya - ilanga, esikhipha, ikhandlela (ilangabi) - kuyimithombo ezishisayo yokukhanya ebonakalayo.

Isibonelo esilandelayo - electroluminescence. Lapha, amandla okuyinto abangela ekushayweni ukukhanya, ama-athomu atholakala emithonjeni nonthermal. Lapho esithweni kagesi ensimini igesi labika amandla athile kinetic, ama-electron, ushaye ama-athomu (igama elithi "Collide"), futhi amandla angama-athomu ujabule sigcine kakade ngesimo luminescence (electroluminescence).

manje Electroluminescence isetshenziselwa izimpawu ukukhangisa esikhanyayo. By endleleni, le Borealis aurora futhi libhekisela ukubukeka electroluminescence: icala izinhlayiya esikhishwa Sun, bakhangwa kazibuthe iplanethi yethu, sijabulile at imijabo yalo, lazo ukukhanya. Kodwa cathode ray amashubhu e ithelevishini kukhanya cathodoluminescence ngenxa: ziyavutha lapha kubangela electron bombardment.

Chemiluminescence - esinye isibonelo yokukhanya ebonakalayo. Lapha umphumela ukuvutha iba namandla eyakhishwa ngo zamakhemikhali. ukukhanya umthombo lokushisa lokushisa medium lapho itholakala. Isibonelo siyikhonze kanye Firefly nge kancane elikhazimulayo eliluhlaza "flashlight". Khanyisa nezinye: ezinye inhlanzi, amagciwane nezinambuzane. Ngezinye izikhathi ungase ubone ukuvutha abolile izihlahla.

Ezinye yomzimba eqala ukuba kuvuthe ngemva kokuba wadalula ekukhanyeni: iyavuleka amandla, banayo beba imithombo yokukhanya. It - photoluminescence izakhiwo zazo kabanzi upende, izingubo, izimpawu zomgwaqo nokunye.

Izingxenye umbala ukukhanya ebonakalayo isetshenziswa umkhuba Psychology: Green is ukududuza obomvu eyaziwa - Kuvusa, onsomi, abamnyama okwesibhakabhaka - kunalokho, zivimbela ngisho ohlushwayo, nokushoda umbala omhlophe abantu nokucindezeleka ingabe zenzeka. emisebeni Kubonakala isetshenziswa kwezokwelapha (Chromotherapy): isibonelo, ukukhanya yellow isetshenziswa ekwelapheni izifo ezithize iso. ukukhanya Red belashwa izifo ezithize pathology of nezindlala ngokocansi: infantilism, ukungazali, izinkinga zabantu besifazane e abesifazane, amanani enganele imbewu amadoda anaphrodisia. Blue ukukhanya aqede ukulunywa, aphathe diathesis exudative futhi izinhlobo ezahlukene ukopha.
