Polarized Teeb vs Unpolarized Teeb
Polarization yog ib qho tseem ceeb heev uas tau tham hauv yoj txoj kev xav ntawm lub teeb. Cov nyhuv ntawm polarization tsis tshua pom nyob rau hauv lub neej tiag tiag, tab sis qhov no tseem ceeb heev rau kev kawm txog cov yam ntxwv ntawm lub teeb. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo hauv cov txiaj ntsig ntawm polarization, polarized lub teeb thiab lub teeb tsis muaj polarized thiaj li ua tau zoo hauv cov teb xws li niaj hnub thiab classical optics, nthwv dej thiab kev vibrations, acoustics thiab ntau yam haujlwm. Hauv tsab xov xwm no, peb yuav tham txog dab tsi polarization yog dab tsi, lub teeb polarized thiab un-polarized lub teeb yog dab tsi, lawv cov ntsiab lus, qhov txawv ntawm lub teeb polarized, kev siv ntawm polarization, thiab thaum kawg qhov txawv ntawm lub teeb polarized thiab un-polarized lub teeb.
Polarized Teeb
Rau ib tus kom nkag siab lub teeb pom kev zoo, nws yuav tsum xub nkag siab polarization. Polarization tsuas yog txhais tau tias yog hom kev taw qhia ntawm oscillations hauv nthwv dej. Polarization ntawm nthwv dej piav qhia cov kev taw qhia ntawm oscillation ntawm nthwv dej nrog rau kev coj ntawm kev nthuav tawm; Yog li ntawd, tsuas yog transverse nthwv dej tso saib polarization. Lub oscillation ntawm hais nyob rau hauv ib tug longitudinal yoj ib txwm nyob rau hauv cov kev taw qhia ntawm propagation; Yog li ntawd, lawv tsis pom polarization. Muaj peb hom polarization, uas yog linear polarization, ncig polarization, thiab elliptical polarization. Xav txog ib tug nthwv dej taug kev los ntawm qhov chaw. Yog hais tias lub nthwv dej yog ib tug neeg kho tshuab nthwv dej, hais lus tau cuam tshuam los ntawm nthwv dej thiab oscillate. Yog hais tias cov particles oscillate ntawm ib kab perpendicular mus rau cov kev taw qhia ntawm propagation, yoj yog hais tias yuav linearly polarized. Yog hais tias cov particles taug qab ib tug ellipse ntawm ib tug dav hlau perpendicular mus rau lub zog ntawm propagation, lub nthwv dej yog ib tug elliptical polarized nthwv dej. Yog hais tias lub particle taug qab ib lub voj voog ntawm ib lub dav hlau perpendicular mus rau cov kev taw qhia ntawm propagation, ces lub yoj yog hais tias yuav ncig polarized. Cov txheej txheem ntawm polarizing yog ua tiav siv lub polarizer. Lub polarizer yog ib qho khoom siv uas tso cai rau qee feem ntawm cov nthwv dej dhau los ntawm nws.
Un-polarized Teeb
Lub teeb tsis muaj polarized yog lub teeb uas peb pom txhua hnub. Txhua qhov chaw ntawm lub teeb generated raws li photons muaj random cov lus qhia ntawm oscillations nrog rau cov kev taw qhia ntawm propagation. Un-polarized lub teeb muaj kev siv zog ntawm txhua qhov kev taw qhia, txhua lub sijhawm. Yog tias lub teeb tsis muaj polarized raug xa los ntawm lub polarizer, lub teeb polarized tuaj yeem tau txais. Reflection kuj ua rau ib feem ntawm txoj kab polarization nyob rau hauv cov kev taw qhia thaum uas tig mus rau lub reflected nto. Polaroid tsom iav yog siv los ua polarize lub teeb hauv lub neej txhua hnub. Txij li thaum lub teeb pom kev tsuas yog muaj cov kab rov tav hluav taws xob hauv qhov tseem ceeb, Polaroid iav txiav cov kab rov tav siv.
Qhov txawv ntawm Polarized thiab Un-polarized teeb yog dab tsi?
• Lub teeb tsis muaj polarized muaj hluav taws xob nyob hauv txhua qhov kev taw qhia, nyob rau lub sijhawm twg los tau, tab sis lub teeb polarized muaj cov hluav taws xob tiv thaiv tsuas yog nyob rau hauv ib qho kev taw qhia rau lub sijhawm.
• Thaum lub teeb tsis muaj polarized yog polarized, nws ib txwm txo qis hauv kev siv.
• Lub teeb ci muab lub teeb tsis muaj polarized, tab sis nws tsis tuaj yeem tsim cov teeb pom kev zoo polarized yam tsis muaj kev siv lub polarizer.
