Dispersive zog ntawm prism

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

Ib yam li ntawd, lub zog dispersive yog dab tsi?

Kev txhais ntawm dispersive zog .: cov zog ntawm qhov nruab nrab pob tshab los cais cov xim sib txawv ntawm lub teeb los ntawm kev cuam tshuam raws li ntsuas los ntawm qhov sib txawv inrefractivity rau ob qhov kev qhia dav dav sib txawv wavelengths faib los ntawm cov refractivity ntawm qee qhov teev nruab nrab nruab nrab.

Ib yam li ntawd, angular dispersion thiab dispersive zog yog dab tsi? Angular Dispersion :D & DispersivePower : w Lub peev xwm ntawm cov khoom siv ntawm lub prism, kom disperse agiven beam ntawm lub teeb rau hauv nws cov xim constituent, yog ntsuas los ntawm ob qhov ntau D & w; uas txhais tau tias. D = Nws yog qhov sib txawv ntawm cov ces kaum ntawm qhov tsawg kawg nkaus deviations rau apair.

Hauv qhov no, lub zog dispersive ntawm cov khoom ntawm Prism yog dab tsi?

Cov dispersive zog ntawm khoom ntawm a prism txhais tau tias yog qhov piv ntawm angular dispersion nruab nrab ntawm ob lub xim huab cua, rau qhov sib txawv uas tsim los ntawm cov xim.

Lub kaum sab xis ntawm dispersion yog dab tsi?

npe Optics. ib qho kev ntsuas ntawm lub kaum sab xis sib cais ntawm lub teeb rays ntawm txawv wavelength los yog xim traversing ib tug prism los yog diffractiongrating, sib npaug rau tus nqi ntawm kev hloov ntawm lub lub kaum sab xis ofdeviation nrog rau kev hloov pauv inwavelength.
