Qhov ntsuas qhov ntsuas ntawm qhov nruab nrab yog nyob ntawm (rau qee qhov) raws li qhov zaus ntawm lub teeb hla, nrog cov zaus siab tshaj plaws muaj qhov siab tshaj plaws ntawm n. Piv txwv li, nyob rau hauv cov iav zoo tib yam lub refractive Performance index rau violet lub teeb yog hais txog ib feem pua siab tshaj qhov ntawd rau lub teeb liab.
Lub teeb xim twg muaj qhov ntsuas siab tshaj plaws?
Qhov ntsuas siab dua ntawm qhov cuam tshuam txhais tau tias violet lub teeb yog qhov khoov tshaj plaws, thiab liab yog qhov qis tshaj vim nws qhov qis qis ntawm qhov cuam tshuam, thiab lwm yam xim poob rau qhov chaw. nyob nruab nrab ntawm.
xim ntawm lub teeb cuam tshuam li cas?
Tus nqi ntawm refraction nce ntxiv raws li lub wavelength ntawm lub teeb txo qis. Qhov luv wavelengths ntawm lub teeb (violet thiab xiav) qeeb dua thiab ua rau muaj kev khoov ntau dua li qhov ntev wavelengths (txiv kab ntxwv thiab liab).
Puas yog qhov ntsuas qhov ntsuas tsis sib txawv rau cov xim sib txawv?
Qhov ntsuas ntawm qhov sib txawv ntawm qhov sib txawv nrog zaus lossis xim. Ntau zaus tsis hloov raws li lub teeb txav los ntawm ib qho nruab nrab mus rau lwm qhov. Txij li cov zaus tseem tsis hloov pauv, qhov kev hloov pauv ntawm qhov ceev ntawm lub teeb hauv cov khoom yog ncaj qha proportional rau qhov kev hloov ntawm lub wavelength ntawm lub teeb thaum nws mus los ntawm ib qho nruab nrab mus rau lwm qhov.
