Rutherford's alpha particle scattering xyaum sim hloov txoj kev peb xav txog atoms. Rutherford qhia cov kab teeb ntawm alpha hais (uas yog lub nuclei ntawm helium atoms thiab li no zoo them) ntawm nyias kub ntawv ci los kuaj cov qauv no thiab sau tseg yuav ua li cas cov alpha hais. tawg tawg los ntawm foil.
Ib yam li ntawd, Rutherford qhov kev sim ua kom tawg tau qhia dab tsi?
Rutherford qhov kev sim tau pom Lub hav zoov ntawm ib tug nuclear atom - ib tug me me, zoo-them nucleus ncig los ntawm qhov chaw khoob thiab tom qab ntawd ib txheej ntawm electrons los tsim sab nraud ntawm lub atom. Feem ntau ntawm alpha hais ua hla ncaj qha los ntawm cov ntawv ci. Lub atom feem ntau yog qhov chaw khoob.
Ib sab saum toj no, Rutherford scattering formula yog dab tsi? Rau ib tug detector ntawm ib lub kaum ntse ntse hais txog qhov teeb meem beam, tus naj npawb ntawm hais ib chav tsev cheeb tsam tawm tsam lub detector yog muab los ntawm lub Rutherford formula : N(θ)=NinLZ2k2e44r2KE2sin4(θ2)
Dab tsi yog qhov kev sim tawg?
Cov kev sim Nws suav nrog firing alpha hais, zoo them helium nuclei ua los ntawm ob protons thiab ob neutrons, ntawm ib txheej nyias ntawm cov ntawv nyiaj kub. Qhov no yog vim hais tias alpha hais yog qhov zoo thiab zoo li cov nqi sib tw, yog li qhov zoo ntawm cov nucleus deflected alpha hais.
Dab tsi yog qhov xaus ntawm Rutherford qhov kev sim ua ntawv kub?
Kev xaus ntawm Rutherford's tawg tawg kev sim : Feem ntau ntawm qhov chaw hauv lub atom yog khoob vim tias feem ntau ntawm α-particles dhau los ntawm ntawv ci tsis tau deflected. Tsawg heev tau deflected los ntawm lawv txoj kev, qhia tau hais tias tus nqi zoo ntawm lub atom occupies tsawg heev qhov chaw.
Pom zoo:
Dab tsi tshwm sim ntawm Theodor Engelmann qhov kev sim nto moo qhia rau nws uas wavelength S yog tus tsav tsheb zoo tshaj plaws ntawm photosynthesis?
Cov kab mob sib sau ua ke ntau tshaj plaws nyob ze ntawm ib feem ntawm cov alga uas tau nthuav tawm cov xim liab thiab xiav wavelengths. Engelmann qhov kev sim ua kom pom tias lub teeb liab thiab xiav yog lub zog zoo tshaj plaws rau photosynthesis
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Thaum twg Rutherford scattering sim?
1909 Ib yam li ntawd, Rutherford scattering sim yog dab tsi? Rutherford's alpha particle scattering xyaum sim hloov txoj kev peb xav txog atoms. Rutherford qhia cov kab teeb ntawm alpha hais (uas yog lub nuclei ntawm helium atoms thiab li no zoo them) ntawm nyias cov ntawv ci kub los kuaj cov qauv no thiab sau tseg tias alpha hais li cas tawg tawg los ntawm foil.
Dab tsi yog Rutherford qhov kev sim ua kub kub?
Rutherford's Gold Foil Experiment tau ua pov thawj tias muaj qhov chaw me me rau cov atoms, uas tom qab ntawd yuav raug hu ua nucleus ntawm lub atom. Ernest Rutherford, Hans Geiger thiab Ernest Marsden tau ua lawv Cov Ntawv Nyiaj Kub Kub los soj ntsuam cov txiaj ntsig ntawm alpha hais txog qhov teeb meem
