Dispersive zog yog ib qho kev ntsuas ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov qis tshaj plaws uas nkag mus rau prism . Qhov no yog qhia nyob rau hauv lub kaum sab xis ntawm 2 huab wavelengths. Qhov loj dua dispersive zog , qhov ntau dua lub kaum sab xis ntawm lawv, thiab vice-versa.

Kuj paub, ua li cas koj nrhiav tau lub zog dispersive ntawm prism?

Dispersive zog ntawm prism Lub refractive index ntawm cov khoom ntawm lub prism tuaj yeem xam los ntawm kev sib npaug. Qhov twg, D yog lub kaum sab xis ntawm qhov sib txawv yam tsawg kawg nkaus, ntawm no D yog txawv rau xim sib txawv.

Ib yam li ntawd, lub kaum sab xis ntawm prism yog dab tsi? “Qhov lub kaum sab xis nruab nrab ntawm ob qhov chaw ntawm a prism yog lub npe hu ua refracting lub kaum sab xis los yog lub kaum sab xis ntawm prism ” Hauv lwm lo lus, peb hais tias tom qab dhau los prism lub teeb ntawm lub teeb deviates los ntawm ib yam lub kaum sab xis los ntawm nws txoj kev qub. Nws yog lub kaum sab xis ntawm kev sib txawv.

Tsis tas li ntawd, lub zog dispersive ntawm lub lens yog dab tsi?

Dispersive zog yog cov cuab yeej ntawm cov khoom siv, tsis hais nws cov duab. Nws txhais tau tias yog qhov piv ntawm angulardeviation rau qhov sib txawv ntawm cov khoom. Rau kev yooj yim, qee qhov txhais, koj tuaj yeem pom C, D thiab F kab yog suav tias yog liab, daj thiab xiav-violet teeb, feem.

Cauchy qhov tsis tu ncua yog dab tsi?

Cauchy cov equation yog ib qho kev sib raug zoo ntawm qhov refractive index thiab wavelength ntawm lub teeb rau aparticular pob tshab khoom. Nws yog lub npe hu rau tus lej lejAugustin-Louis Cauchy , leej twg txhais nws nyob rau hauv 1836. Qhov twg A thiab Bare hu ua Cauchy qhov tsis tu ncua rau prism.
