Refractive index hauv qab kev sib koom ua ke Cov theem tshaj tawm yog qhov ceev ntawm cov crests ntawm nthwv dej txav thiab tuaj yeem nrawm dua qhov nrawm ntawm lub teeb hauv lub tshuab nqus tsev, thiab yog li muab qhov ntsuas pom hauv qab 1. Qhov no tuaj yeem tshwm sim ze rau resonance. frequencies, rau absorbing media, hauv plasmas, thiab X-rays.
Yuav ua li cas thaum qhov ntsuas qhov ntsuas ntawm qhov sib txawv yog sib npaug rau 1?
Formula 1 - Snell's Law
Xwb thaum n(2) ntau dua n(1) lub kaum sab xis ntawm refraction ib txwm me dua lub kaum sab xis ntawm qhov xwm txheej. Thaum ob lub refractive indices sib npaug (n(1)=n(2)), ces lub teeb hla dhau yam tsis muaj refraction.
Yuav ua li cas rov qab qhov ntsuas tau 1 piav qhia?
Refractive index of a nruab nrab yog ib txwm siab dua 1 (nws tsis tuaj yeem tsawg dua 1) vim tias qhov ceev ntawm lub teeb nyob rau hauv ib qho nruab nrab yog ib txwm tsawg dua li hauv lub tshuab nqus tsev.
Puas qhov Performance index ntawm refraction tsawg dua 1?
Refractive indices tsawg dua 1 tuaj yeem tshwm sim thiab yog tias theem tshaj tawm ntawm lub teeb hauv nruab nrab yog nrawm dua qhov nrawm ntawm lub teeb. … Tsis zoo refractive indices tuaj yeem tshwm sim yog tias ob qho tib si permittivity thiab permeability ntawm cov khoom yog ob qho tib si tsis zoo tib lub sijhawm.
Dab tsi yog chav ntsuas ntawm qhov ntsuas qhov taw qhia?
refractive index tsis muaj si units, txij li los ntawm lub ntsiab lus refractive index yog qhov piv ntawm qhov nrawm ntawm lub teeb hauv cov khoom faib nrog qhov nrawm ntawm lub teeb hauv lub tshuab nqus tsev. qhov no yog qhov meant los ntawm"integral". … thiab qhov piv ntawd yog qhov ntsuas qhov taw qhia.
