Siv. Cov tshuaj no yog cov khoom siv multivitamin siv los kho lossis tiv thaiv vitamin deficiency vim noj zaub mov tsis zoo, qee yam mob, lossis thaum cev xeeb tub. Cov vitamins yog ib qho tseem ceeb hauv lub cev thiab pab kom koj noj qab nyob zoo.
Tsis tas li ntawd, spectrum txhais li cas?
A spectrum (plural spectrum los yog spectrums) yog ib yam mob uas tsis txwv rau ib qho tshwj xeeb ntawm qhov tseem ceeb tab sis tuaj yeem sib txawv, tsis muaj cov kauj ruam, hla ib qho txuas ntxiv. Lo lus yog thawj zaug siv scientific hauv optics los piav txog zaj sawv ntawm cov xim nyob rau hauv pom lub teeb tom qab dhau los ntawm ib tug prism.
Ib yam li ntawd, lub electromagnetic spectrum yooj yim txhais yog dab tsi? Txhais ntawm electromagnetic spectrum .: tag nrho ntau ntawm wavelengths lossis frequencies ntawm electromagnetic tawg txuas ntawm gamma rays mus rau lub xov tooj cua ntev tshaj plaws nthwv dej thiab suav nrog lub teeb pom kev.
Cov lus nug tseem yog, hom spectrum yog dab tsi?
Muaj peb hom spectra uas ib yam khoom yuav emit: nruam, emission thiab absorption spectra. Cov piv txwv ntawm cov hom spectra qhia hauv qab no yog rau pom lub teeb raws li nws tau nthuav tawm los ntawm ntshav mus rau liab, tab sis lub tswv yim yog tib yam rau txhua cheeb tsam ntawm electromagnetic spectrum.
Dab tsi yog electromagnetic spectrum siv rau?
Yuav luag txhua zaus thiab wavelengths ntawm electromagnetic hluav taws xob tuaj yeem ua tau siv rau spectroscopy. Xov tooj cua nthwv dej, rays infrared, pom lub teeb, ultraviolet rays, X-rays, thiab gamma rays yog txhua yam. electromagnetic hluav taws xob. Xov tooj cua tsis muaj qhov ntev tshaj plaws wavelength, thiab gamma rays muaj qhov luv tshaj wavelength.
