Txhawm rau txiav txim siab Dispersive zog ntawm prism:

  1. Tig lub rooj vernier thiaj li poob lub teeb los ntawm lub collimator mus rau ib lub ntsej muag ntawm lub prism thiab tau tshwm sim los ntawm lwm lub ntsej muag.
  2. Tig lub telescope kom lub slit coincide nrog telescopecross hlau.
  3. Cov hluav taws xob tawm muaj xim sib txawv.

Ib yam li ntawd, nws yog nug, dab tsi yog lub zog dispersive ntawm prism?

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 hauv prism . Qhov loj dua dispersive zog , qhov ntau dua lub kaum sab xis ntawm lawv, thiab vice-versa.

Kuj Paub, dab tsi yog xim prism? Prisms tuaj yeem ua los ntawm txhua yam khoom uas yog pob tshab rau lub wavelengths uas lawv tsim. Cov khoom siv xws li iav, yas, thiab fluorite. Ib tug dispersive prism tuaj yeem siv los rhuav lub teeb rau hauv nws cov constituentspectral xim (cov xim ntawm zaj sawv).

Ntawm no, dab tsi yog tus qauv ntawm dispersive zog?

tus dr) / (dy) yog lub npe hu ua dispersive zog ntawm cov khoom ntawm prism thiab yog denoted los ntawm ω. The dispersive zog ntawm cov khoom ntawm ib tug prism yog txhais raws li qhov piv ntawm angular kev tawg rau ob lub wavelengths (xim) rau qhov sib txawv ntawm qhov nruab nrab wavelength.

Muaj pes tsawg xim muaj nyob rau hauv prism?

COLOR SPECTRUM Cov neeg feem coob tuaj yeem pom tsuas yog xya qhov sib txawv xim nyob rau hauv spectrum: liab, txiv kab ntxwv, daj, ntsuab, xiav, indigo, thiab violet. Ib yam li ib prism tuaj yeem faib lub teeb dawb rau hauv qhov sib txawv xim , yog li lub teeb ntawm cov xim sib txawv tuaj yeem muab ntxiv ua ke ua kom lub teeb dawb.
