Reflection cuam tshuam nrog kev hloov pauv ntawm nthwv dej thaum lawv dhia tawm ntawm qhov thaiv. Kev cuam tshuam ntawm nthwv dej cuam tshuam nrog kev hloov pauv ntawm cov nthwv dej thaum lawv dhau los ntawm ib qho nruab nrab mus rau lwm qhov. Refraction, los yog khoov ntawm txoj kev ntawm cov nthwv dej, yog nrog los ntawm kev hloov pauv ntawm qhov nrawm thiab lub zog ntawm cov nthwv dej.
YPuas yog kev xav thiab kev cuam tshuam zoo ib yam?
Reflection yog qhov rov qab ntawm lub teeb thaum nws tawm tsam qhov chaw du. Refraction yog qhov khoov ntawm lub teeb rays thaum nws mus los ntawm ib qho nruab nrab mus rau lwm qhov.
Puas yog daim iav refraction lossis reflection?
Daim iav tsis thim daim duab sab laug mus rau sab xis; nws thim rov qab rau pem hauv ntej. Piv txwv li, yog tias koj tig mus rau sab qaum teb, koj qhov kev xav yog tig mus rau sab qab teb. Qhov kev xav ntawm lub teeb rays yog ib qho tseem ceeb ntawm geometric optics; Lwm qhov yog refraction, lossis khoov ntawm lub teeb rays.
Yuav ua li cas yog qhov kev xav thiab refraction muaj sib xws?
Reflection thiab refraction yog ob qho tib si tus cwj pwm ntawm nthwv dej, xws li lub teeb thiab lub suab nthwv dej. … Thaum thaws tawm ntawm tej qhov chaw, teeb pom kev nyob rau hauv tib lub kaum sab xis thaum nws tsoo saum npoo. Ci ntsa iab, ntxhib qhov chaw ua rau lub teeb pom kev hauv txhua qhov kev taw qhia.
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kev xav thiab thim rov qab?
Nyob rau hauv kev xav, nthwv dej tawm ntawm qhov chaw. Ntawm qhov tsis sib xws, nyob rau hauv refraction, nthwv dej dhau los ntawm qhov chaw, uas hloovlawv ceev thiab kev taw qhia. Hauv kev xav, lub kaum sab xis ntawm qhov xwm txheej yog tib yam li lub kaum sab xis ntawm kev xav. Raws li tawm tsam qhov no, lub kaum sab xis ntawm qhov xwm txheej tsis zoo ib yam li lub kaum sab xis ntawm qhov cuam tshuam.
