Thaum lub teeb hluav taws xob nkag mus rau qhov nruab nrab refracting, nws pom tau tias qhov loj ntawm lub kaum sab xis ntawm refraction yog sib npaug rau ib nrab ntawm lub kaum sab xis ntawm kev xav.
Thaum lub teeb ci nkag los ntawm ib qho nruab nrab mus rau lwm qhov nruab nrab raws li ib txwm muaj?
Refraction yog ib qho tshwm sim thaum lub teeb nthwv dej, tshwm sim ntawm lub kaum sab xis ntawm qhov qub, hla ib thaj tsam ntawm ib nrab mus rau lwm qhov uas muaj kev hloov pauv hauv ceev ntawm lub teeb. Lub teeb yog refracted thaum nws hla lub interface ntawm huab cua mus rau hauv iav uas nws txav tau qeeb dua.
Thaum lub teeb ci nkag mus rau lwm qhov nruab nrab nws hu ua dab tsi?
Yog lub teeb rays taug kev los ntawm ib qho nruab nrab mus rau lwm qhov lawv hloov lawv txoj kev coj ntawm tus ciam teb ntawm ob qhov nruab nrab. Thaum lub teeb rays yog khoov los yog hloov lawv cov kev taw qhia thaum hla ntawm ib qho nruab nrab mus rau lwm qhov nws yog hu ua refraction of light.
Thaum lub teeb ci nkag mus rau qhov nruab nrab uas ntau dua?
Lub teeb yog refracted (khoov) nkaus xwb ntawm qhov sib cuam tshuam ntawm ob lub pob tshab ntawm qhov sib txawv. Lub teeb dhau los ntawm qhov tsawg dua mus rau ntau dua dense nruab nrab khoov mus rau qhov qub.
Vim li cas lub teeb refract thaum nws nkag mus rau qhov nruab nrab?
Kev khoov ntawm lub teeb thaum nws dhau los ntawm ib qho nruab nrab mus rau lwm qhov yog hu ua refraction. Lub kaum sab xis thiab wavelength uas lub teeb nkag mus rau ib yam khoom thiab qhov ntom ntawm cov khoom ntawdtxiav txim siab npaum li cas lub teeb yog refracted. … Kev khoov tshwm sim vim lub teeb mus qeeb dua hauv qhov nruab nrab denser.
