Txhua cov nthwv dej electromagnetic yog transverse nthwv dej thiab lawv tuaj yeem ua polarized. Tsuas yog longitudinal yoj longitudinal yoj Mechanical longitudinal wavestseem hu ua compressional lossis compression nthwv dej, vim tias lawv tsim compression thiab rarefaction thaum taug kev los ntawm qhov nruab nrab, thiab lub siab nthwv dej, vim lawv tsim thiab txo qis. siab. https://en.wikipedia.org › wiki › Longitudinal_wave

hauv kev xaiv yog ultrasonic yoj uas yog lub suab nthwv dej. Yog li cov nthwv dej ultrasonic tsis tau polarized.
Yuav ua li cas tsis tuaj yeem polarized?
Tsis zoo li cov nthwv dej hla xws li cov nthwv dej electromagnetic, ntev nthwv dej xws li suab nthwv dej tsis tuaj yeem polarized. Lub polarization ntawm nthwv dej yog muab los ntawm kev taw qhia ntawm oscillations hauv qhov chaw nrog rau qhov cuam tshuam nruab nrab. Lub polarized nthwv dej vibrates hauv ib lub dav hlau hauv qhov chaw.
Yuav ua li cas hauv qab no tuaj yeem ua polarized?
Transverse nthwv dej tuaj yeem oscillate nyob rau hauv cov kev taw qhia perpendicular rau lawv cov kev taw qhia kis tau tus mob, tab sis longitudinal nthwv dej oscillate tsuas yog raws cov kev taw qhia ntawm lawv kis tau tus mob. Cov nthwv dej hlais no hu ua S- nthwv dej los yog cov nthwv dej, thiab yog, lawv tuaj yeem ua polarised.
xov tooj cua puas tuaj yeem polarized?
Yes, xov tooj cua tsis tuaj yeem polarized vim tias xov tooj cua tsis yog ib hom hluav taws xob nthwv dej uas muaj hluav taws xob thiab cov hlau nplaum sib nqus traversing perpendicular mus rau ib leeg thiab perpendicular mus rau cov kev taw qhia ntawm lub zog ntawm yoj (nce thiab nqis los yog ib sab ntawm ib sab). Yog li ntawd, xov tooj cua tsis muaj peev xwm yuav polarised.
Qhov twg hauv qab no Tsis tuaj yeem tsim lub teeb polarized?
Plag: Diffraction of light tsis tuaj yeem hloov lub teeb tsis muaj polarized rau hauv lub teeb polarized. Polarization yog txhais raws li ib tug tshwm sim tshwm sim vim yoj xwm ntawm electromagnetic hluav taws xob. Hnub ci taug kev los ntawm lub tshuab nqus tsev mus txog lub ntiaj teb, uas yog ib qho piv txwv ntawm ib qho hluav taws xob nthwv dej.
