Teeb thiab teeb meem cuam tshuam rau ib leeg hauv ntau txoj hauv kev. Kev sib cuam tshuam ntawm teeb thiab teeb meem txiav txim qhov tsos ntawm txhua yam nyob ib puag ncig peb. Teeb cuam tshuam nrog teeb meem nyob rau hauv txoj kev xws li emission thiab absorption. Cov nyhuv photoelectric yog ib qho piv txwv ntawm yuav ua li cas teeb meem nqus teeb.

Tsis tas li ntawd, lub teeb thiab teeb meem cuam tshuam li cas?

Teeb meem yog tsim los ntawm cov nqi them vim qhov xwm ntawm atoms, yog tsim los ntawm ib tug zoo nqi nucleus ncig los ntawm electrons uas nyob rau hauv kev txav. Tab sis teeb kuj yog ib tug particle - nws cov particle yog hu ua ib tug photon thiab txhua photon nqa ib pob ntawv ntawm lub zog uas yog proportional rau lub zaus.

Ib yam li ntawd, koj puas tuaj yeem pom lub teeb yam tsis muaj lub teeb cuam tshuam nrog teeb meem? Kev sib tham ntawm teeb nrog teeb meem nyob rau hauv uas cov hais ntawm teeb meem nqus teeb zog so teeb tsis muaj kev cuam tshuam los ntawm kev hla dhau teeb meem . Hais txog teeb meem uas ua tsis yog tso cai pom teeb mus dhau ntawm nws vim nws xav txog lossis nqus tag nrho cov teeb.

Ntawm no, yuav ua li cas rau lub teeb thaum nws cuam tshuam nrog teeb meem?

Thaum twg Lub teeb cuam tshuam nrog teeb meem nws tuaj yeem ua ib qho ntawm ob peb yam, nyob ntawm nws qhov wavelength thiab hom twg teeb meem nws ntsib: nws tuaj yeem kis tau, cuam tshuam, refracted, diffracted, adsorbed lossis tawg. Thaum no tshwm sim tus teeb qeeb thiab hloov kev taw qhia.

Dab tsi yog plaub txoj kev loj thiab teeb meem tuaj yeem cuam tshuam?

Cov plaub txoj kev loj thiab teeb meem tuaj yeem cuam tshuam yog los ntawm emission, absorption, kis, thiab reflection/scattering. lub zog yog tawm los ntawm lub teeb.
