Cov Txheej Txheem Ntawm Cov Xim Tiam Ntawm Cov Neeg Sawv Cev Hlau Cov Khoom Hlau

Tus txheej txheem kev hloov xim ntawm cov neeg xyuas pib cov ntaub ntawv hlau

Ntawm cov hlau uas ua txog plaub feem tsib ntawm cov khoom hauv qhov xwm, tshwj tsis yog ntawm ob peb, xws li kub, tooj liab, thiab bismuth, uas yog xim daj, txhua yam yog silvery lossis tawm-dawb ci ci opaque solids (mercury yog kua). Qhov no yog vim qhov xwm ntawm txhua yam khoom siv yog lub zog sib npaug ntawm lub cev, cov hlau yog tsim los ntawm cov xim hlau sib txuas ua ke nrog cov siv lead ua hlau, tsuas yog sab hauv cov hlau dawb electrons lossis resonant zaus sib raug rau cov zaus zaus ntawm pom lub teeb. , thiaj li yooj yim kom nqus tau qhov pom pom ntawm qee qhov hloov zaus lub zog hloov, tuaj txog ntawm theem siab dua, nyob rau hauv lub xeev ntawm flux, tom qab ntawd nws qhov kev hloov pauv rov qab mus rau thawj theem, tom qab ntawd mus rau sab nraud hluav taws xob nyob rau hauv daim ntawv ntawm lub teeb.Tab sis feem ntau hlau free electrons nqus tag nrho cov wavelengths (frequencies) ntawm lub teeb pom thiab tom qab ntawd rov tsom lawv rov qab yuav luag tag nrho, yog li cov hlau feem ntau yog nyiaj-dawb lossis tawm-dawb. Txawm li cas los xij, ob peb cov khoom siv hlau nqus ib co wavelength ntawm lub teeb nyob rau hauv lub teeb pom mus rau ntau dua, thiab lwm qhov yoj yoj ntawm lub teeb mus rau qhov qis dua, yog li cov hlau yuav siv tshwj xeeb xim. Hauv tooj liab, piv txwv li, txoj hlua khawm coj ua tsuas yog ib nrab puv. Lub zog npliag nyob sib ze nrog qib kev nyab xeeb. Hluav taws xob nqus pom lub teeb pom kev yooj yim. Nws tuaj yeem paub los ntawm cov nplaim hluavtaws cov tshuaj tiv thaiv uas lawv mas nqus lub teeb ntsuab. Thaum txhua tus hlau nyob hauv lub xeev cov hmoov, lub ntsej muag siv lead ua ntawm cov hlau yog qhov sib txawv heev thiab cov khoom siv lead ua raug teeb tsa tsis xwm yeem. Txhua lub teeb pom kev pom tsis tuaj yeem tawm tsis tau. Yog li no, cov hlau feem ntau dub hauv cov xeev hmoov.
