Dispersion txhais tau tias yog kev sib kis ntawm lub teeb dawb rau hauv nws cov spectrum tag nrho ntawm wavelengths. Ntau technically, kev tawg tshwm sim thaum twg muaj cov txheej txheem uas hloov cov kev taw qhia ntawm lub teeb nyob rau hauv ib yam uas nyob ntawm wavelength.
Ces, dispersion teb yog dab tsi?
Teb . Dispersion yog qhov tshwm sim nyob rau hauv uas theem tshaj tawm ntawm nthwv dej nyob ntawm nws qhov zaus. Wave nrog ntau zaus yog diffracted ntau tshaj cov uas muaj tsawg zaus.
Ib yam li ntawd, dispersion yog dab tsi thiab nws hom? Hauv qhov nruab nrab kho qhov muag, xws li fiber ntau, muaj peb hom ntawm kev tawg , chromatic, modal, thiab khoom siv. Chromatic Dispersion . Chromatic kev tawg tshwm sim los ntawm spectral dav ntawm lub emitter. Qhov dav spectral txiav txim seb tus naj npawb ntawm cov wavelengths sib txawv uas tawm ntawm LED lossis laser.
Tsis tas li ntawd, koj txhais li cas los ntawm lub sij hawm dispersion?
Dispersion yog ib qho kev txheeb cais lub sij hawm uas piav txog qhov loj ntawm qhov kev faib tawm ntawm cov txiaj ntsig xav tau rau ib qho kev sib txawv. Dispersion tau ntsuas los ntawm ntau yam kev txheeb cais, xws li ntau yam, qhov sib txawv, thiab tus qauv sib txawv.
Dab tsi yog qhov zoo li dispersion?
Kev txhais ntawm ib txwm dispersion .: kev tawg (raws li lub teeb los ntawm ib qho kev kho qhov muag grating) nyob rau hauv uas kev sib cais ntawm cov khoom nyob rau hauv ib tug spectrum nce mus tas li thiab yuav luag uniformly nrog lub wavelength, qhov kev sib cais yog ib tug monotonic muaj nuj nqi ntawm lub kev tawg sib txawv.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dispersion ntawm lub teeb yog dab tsi yog vim li cas?
Qhov sib cais ntawm lub teeb dawb rau hauv nws cov xim xim ntawm kev hla dhau ntawm qhov nruab nrab refracting zoo li iav prism hu ua dispersion ntawm lub teeb. Lub dispersion ntawm lub teeb dawb tshwm sim vim cov xim sib txawv ntawm lub teeb khoov los ntawm cov ces kaum sib txawv nrog rau qhov teeb meem ntawm lub teeb, raws li lawv dhau los ntawm lub prism
Dispersion ntawm lub teeb luv teb yog dab tsi?
Teb Chaws Asmeskas: Dab tsi yog qhov tawg ntawm lub teeb? Lub dispersion ntawm lub teeb yog qhov tshwm sim ntawm kev sib cais ntawm ib lub teeb ntawm lub teeb dawb rau hauv nws cov xim xim thaum dhau los ntawm qhov nruab nrab pob tshab. Nws tau pom los ntawm Isaac Newton hauv xyoo 1666
Uniform dispersion yog dab tsi?
Clumped dispersion yog thaum cov tib neeg hauv cov pej xeem tau sib sau ua ke, tsim qee thaj ua rau muaj ntau tus neeg thiab qee thaj tsam tsis muaj tib neeg. Nyob rau hauv uniform dispersion, cov tib neeg yog spaced tusyees thoob plaws hauv ib cheeb tsam. Thiab nyob rau hauv random dispersion, cov tib neeg raug teeb tsa yam tsis muaj qhov pom tseeb
Dab tsi yog qhov txawv ntawm dipole dipole thiab London dispersion?
Thaum tag nrho cov molecules yog attracted rau ib leeg, qee qhov kev nyiam muaj zog dua lwm tus. Tsis-polar molecules yog attracted los ntawm London dispersion attraction; polar molecules yog attracted los ntawm ob qho tib si London dispersion quab yuam thiab lub zog dipole-dipole attraction
