Ib qho hluav taws xob nthwv dej xws li lub teeb muaj cov hluav taws xob sib txuas ua ke thiab cov hlau nplaum sib nqus uas ib txwm nyob rau ib leeg; los ntawm lub rooj sib tham, "polarization" ntawm electromagnetic nthwv dej hais txog kev taw qhia ntawm hluav taws xob teb. … Qee qhov no yog siv los ua cov lim dej polarizing.
Vim li cas thiaj li electromagnetic tsis polarized?
Yog, xov tooj cua tsis tuaj yeem polarized vim xov tooj cua nthwv dej yog ib hom hluav taws xob nthwv dej uas muaj hluav taws xob thiab hlau nplaum traversing perpendicular mus rau ib leeg thiab tseem perpendicular rau cov kev taw qhia ntawm lub zog ntawm nthwv dej (nce thiab nqis los yog ib sab ntawm ib sab).
Kev taw qhia ntawm polarization ntawm electromagnetic yoj yog dab tsi?
Kev taw qhia ntawm polarization txhais tau tias yog kev coj mus rau qhov hluav taws xob ntawm EM nthwv dej. Lub teeb tsis muaj polarized yog tsim los ntawm ntau lub rays uas muaj cov lus qhia random polarization.
electromagnetic yoj yog dab tsi thiab nws tuaj yeem ua polarized li cas?
Peb faib electromagnetic yoj polarization li linearly polarizedlos yog ncig polarized, nyob ntawm seb lub hluav taws xob vector tswj qhov kev taw qhia ruaj khov hauv qhov chaw (linear polarization) lossis rotates nyob ib ncig ntawm cov kev taw qhia vector (cov xub liab) nyob rau hauv rooj plaub ntawm ncig polarization.
koj txhais li cas los ntawm polarization?
1: kev ua ntawm polarizing lossis lub xeev ntawm kev ua lossisua polarized: xws li. a(1): qhov kev txiav txim lossis cov txheej txheem ntawm kev cuam tshuam hluav taws xob thiab tshwj xeeb tshaj yog lub teeb kom cov kev vibrations ntawm nthwv dej xav tau ib daim ntawv meej.
