Thaum lub teeb pom kev tshwm sim ntawm qhov xwm txheej ib txwm muaj, (ntawm lub kaum sab xis), mus rau saum npoo ntawm ob qho khoom siv kho qhov muag, lub teeb ci mus rau hauv txoj kab ncaj nraim Thaum lub teeb ci yog xwm txheej ntawm lwm lub kaum sab xis, txoj kab hluav taws xob hloov kev taw qhia raws li nws refracts. Cov kab dotted yog qhov qub (perpendicular) rau saum npoo.
Lub kaum sab xis ntawm qhov xwm txheej yog dab tsi rau qhov xwm txheej ntawm lub teeb?
Thaum teeb meem hluav taws xob raws ib qho hluav taws xob ib txwm ua rau 90∘ kaumnrog lub npoo ntawm 0∘ kaum nrog nws tus kheej.
Lub kaum sab xis ntawm kev xav yog dab tsi hauv qhov xwm txheej ib txwm muaj?
Thaum lub teeb hluav taws xob tshwm sim ib txwm ntawm lub dav hlau daim iav nto nws txhais tau tias lub kaum sab xis ntawm daim iav saum npoo thiab lub teeb hluav taws xob yog 90°.
Dab tsi yog qhov xwm txheej ib txwm muaj?
Ib txwm muaj xwm txheej yog qhov xwm txheej uas lub kaum ntse ntse ntawm qhov xwm txheej yog xoom, lub wavefront yog tib yam rau saum npoo thiab nws cov raypath yog perpendicular, los yog ib txwm, rau lub interface. Snell txoj cai piav qhia txog kev sib raug zoo ntawm lub kaum sab xis ntawm qhov xwm txheej thiab lub kaum sab xis ntawm refraction ntawm nthwv dej.
kaum ntawm qhov xwm txheej yog dab tsi?
Lub kaum ntse ntse - lub kaum sab xis uas qhov teeb meem hluav taws xob ua nrog qhov qubyog hu ua kaum ntawm qhov xwm txheej. Lub kaum sab xis ntawm refraction - Lub kaum sab xis uas cov hluav taws xob refracted ua nrog qhov qub yog hu ua lub kaum sab xis ntawm refraction.
