Yog li kev xaiv lub teeb los ntawm cov khoom siv tshwj xeeb tshwm sim vim qhov zaus ntawm lub teeb nthwv dej sib tw nrog qhov zaus ntawm cov electrons hauv atoms ntawm cov khoom ntawd vibrate. Absorption nyob ntawm lub xeev ntawm ib yam khoom electron.
Vim li cas lub teeb pom kev lossis nqus tau?
Kev cuam tshuam thiab xa tawm ntawm lub teeb nthwv dej tshwm sim vim qhov zaus ntawm lub teeb tsis sib haum nrog lub ntuj frequencies ntawm kev co ntawm cov khoomThaum lub teeb nthwv dej ntawm cov frequencies no ntaus ib yam khoom, cov electrons hauv atoms ntawm cov khoom pib vibrating.
Puas lub teeb ib txwm nqus tau?
Feem ntau tsis yog tag nrho lub teeb yog absorbed los ntawm ntothiab lub teeb uas tsis absorbed yog tawg. Peb kuj pom tau hais tias lub teeb uas absorbed muaj ib tug wavelength nyob ntawm seb qhov xwm ntawm qhov chaw, xws li cov khoom uas nws yog thiab dab tsi dyes tej zaum yuav tau ntxiv rau nws.
Yog lub teeb tso tawm lossis nqus tau?
Thaum cov hluav taws xob rov qab mus rau qis zog, lawv tso lub zog ntxiv thiab qhov ntawd tuaj yeem ua rau lub teeb ua rau lub teeb ci. Ntawm qhov tod tes, absorbed lub teeb yog qhov tsis pom. Absorption tshwm sim thaum electrons nqus photons uas ua rau lawv nce zog thiab dhia mus rau qib siab zog.
Lub cev nqus tau lub teeb li cas?
pom lub teeb feem ntau yog tawg thiab tsuas yog nqus tau los ntawm qee yam xws li cov xim thiab cov ntshavCov xim hauv cov hlwb tshwj xeeb hauv qhov muag nqus pom hluav taws xob, ua rau lub teeb liab hluav taws xob mus. los ntawm cov hlab ntsha kho qhov muag mus rau lub hlwb thiab tso cai rau peb pom hauv cov xim.
