Teb: Suab nrov , yog longitudinal, txhais tau hais tias lawv oscillate parallel rau cov kev taw qhia ntawm lawv cov lus tsa suab. Vim tsis muaj ib feem ntawm a suab yoj oscillation uas yog perpendicular rau nws cov lus tsa suab, suab tsis tuaj yeem polarized.

Ua raws li qhov no hauv kev xav, cov suab tsis tuaj yeem Polarised?

Suab nrov yog longitudinal ces lawv yuav tsis tau polarized . Unpolarised: lub yoj vibrations tshwm sim nyob rau hauv tag nrho cov dav hlau perpendicular rau cov kev taw qhia ntawm kev mus ncig.

Kuj Paub, qhov twg ntawm cov nthwv dej hauv qab no Tsis tuaj yeem polarized? Tag nrho cov longitudinal nthwv dej zoo li suab thiab lwm yam tsis tuaj yeem polarized vim qhov kev txav ntawm cov khoom yog twb nyob rau hauv ib dimension uas yog cov kev taw qhia ntawm propogation ntawm yoj . Yog li tag nrho cov transverse nthwv dej zoo li electromagnetic nthwv dej tuaj yeem yog polarized.

Ib yam li ntawd, vim li cas qee qhov nthwv dej tuaj yeem Polarized thiab lwm tus tsis?

Thaum transverse nthwv dej muaj lawv hais ib txwm vibrating nyob rau hauv tib lub dav hlau, lub yoj hais tias yog "plane polarized ". Ntev vuag tau tsi be polarized vim hais tias lawv hais vibrate nyob rau hauv tib txoj kev uas cov yoj taug kev. Vuag txav zog los ntawm qhov nruab nrab tsis muaj txav tag nrho nruab nrab.

Cov suab tsis tuaj yeem cuam tshuam?

Kev cuam tshuam ntawm Suab . Ob tug taug kev nthwv dej uas muaj nyob hauv tib qhov nruab nrab yuav cuam tshuam nrog ib leeg. Yog hais tias lawv amplitudes ntxiv, lub cuam tshuam yog hais tias tsim nyog cuam tshuam , thiab kev puas tsuaj cuam tshuam yog tias lawv "tawm ntawm theem" thiab rho tawm.
