Lub teeb ci ntsa iab Polarized: Lub teeb ci tau tso cai rau poob rau a Nicol prism. Yog hais tias ntawm kev sib hloov ntawm Nicol prism qhov kev siv ntawm emission teeb tseem zoo ib yam, ces lub teeb yog ib ncig polarized los yog unpolarised.
Yuav ua li cas koj thiaj paub yog lub teeb yog ncig polarized?
Yog lub teeb yog tsim los ntawm ob lub dav hlau nthwv dej ntawm qhov sib npaug ntawm qhov sib npaug tab sis txawv nyob rau theem los ntawm 90 °, ces lub teeb tau hais tias yuav tsum tau voj voog polarized. Yog tias koj tuaj yeem pom qhov ntxeev ntawm qhov hluav taws xob hluav taws xob vector, nws yuav zoo li txav mus rau hauv lub voj voog thaum nws los ze koj. … Yog clockwise, ces sab laug-civ polarized teeb.
Koj pom lub voj voog polarization li cas?
Lub teeb ci ib puag ncig tuaj yeem hloov mus ua linearly polarized lub teeb los ntawm kev hla nws hla lub quarter-waveplate. Tshaj tawm lub teeb ci polarized los ntawm lub quarter-waveplate nrog nws cov axes ntawm 45 ° rau nws cov polarization axis yuav hloov nws mus rau lub voj voog polarization.
Koj ua li cas txiav txim siab qhov kev tes ntawm lub teeb elliptical polarized?
Yog tias ob qho tib si muaj qhov sib npaug thiab qhov hloov pauv theem ntawm y tivthaiv rau x tivthaiv yog + π / 2 lossis -π / 2, lub teeb yog ncig polarized. Lub kos npe ntawm theem sib txawv txiav txim siab qhov kev sib hloov ntawm tes.
Pab tes polarization yog dab tsi?
voj voog polarization ntawm electromagnetic yoj nyob rau hauv uas lub hluav taws xob teb vector rotates nyob rau hauv ib tug counterclockwise kev taw qhia, raws li pom los ntawm ib tug soj ntsuam saib nyob rau hauv cov kev taw qhia ntawm propagation ntawm yoj. Synonym sab laug ncig polarization.
