Taw qhia rau spectroscopy
Spectroscopy yog ib qho kev kawm sib txawv tseem ceeb uas feem ntau siv physics thiab chemistry. Nws siv spectroscopy los kawm txog kev cuam tshuam ntawm electromagnetic vuag thiab teeb meem. Teeb yog hluav taws xob hluav taws xob hluav taws xob superimposed los ntawm hluav taws xob tsis muaj hluav taws xob ntawm ntau lub wavelengths (lossis ntau zaus). Lub spectrum yog ib hom graph uas siv kev sib kis, prism, Fourier kev hloov pauv thiab lwm qhov kev txhais tau zoo los soj ntsuam qee yam khoom ntawm lub nqaj ntawm cov hluav taws xob hluav taws xob rau hauv kev sib koom ua ke ntawm txhua ntu hluav taws xob ntawm cov hluav taws xob rau cov cuab yeej no. Piv txwv, qhov nqus spectrum tuaj yeem teev qhov nqus kev nqus ntawm ib yam khoom rau lub zog sib xws ntawm cov yoj yoj ib qho sib npaug ntawm cov nthwv dej los ntawm qis rau siab yoj yoj.
