Perpendicular Polarization (Transverse Hluav taws xob ) - Qhov no tshwm sim thaum sib nqus field isparallel rau lub dav hlau ntawm qhov xwm txheej , mas cov hluav taws xob fieldis perpendicular rau lub dav hlau ntawm qhov xwm txheej . Qhov no tseem hu ua 'S-polarized' lub teeb, lub 's' los ntawm lo lus German rau perpendicular , kev.

Ntawm no, dab tsi yog parallel polarization?

Parallel polarization (Transverse Magnetic) - Meanwhile, thaum uas tig mus polarization yog qhov opposite. Qhov no tshwm sim thaum hluav taws xob fiels yog thaum uas tig mus mus rau lub dav hlau ntawm qhov tshwm sim thiab lub magnetic teb yog perpendicular.

Tsis tas li ntawd, Fresnel coefficients sawv cev li cas? Cov Fresnel equations (los yog Fresnelcoefficients ) piav qhia txog qhov kev xav thiab kev sib kis ntawm lub teeb (lossis hluav taws xob hluav taws xob feem ntau) thaum muaj xwm txheej ntawm qhov cuam tshuam ntawm cov xov xwm sib txawv.

Ib yam li ntawd, oblique tshwm sim yog dab tsi?

165. Oblique xwm txheej : Interface ntawm dielectric media. Xav txog ib qho kev sib tham ntawm cov xov xwm twodielectric. Lub dav hlau yoj yog xwm txheej ntawm lub kaum sab xis ntawm nruab nrab 1.

Vim li cas Brewster lub kaum sab xis hu ua polarizing kaum?

Brewster lub kaum sab xis feem ntau hu ua " polarizing lub kaum sab xis ", vim tias lub teeb uas cuam tshuam los ntawm qhov chaw ntawm qhov no lub kaum sab xis yog kiag li polarized perpendicular rau lub dav hlau ntawm qhov xwm txheej ("s- polarized "). Nyob rau hauv cov ntaub ntawv ntawm kev xav ntawm Brewster lub kaum sab xis , lub reflected thiab refracted rays yog kev sib nrig sib perpendicular.
