yog tias electron yog (particle) subatomic particle uas muaj tus nqi tsis zoo thiab orbiting lub nucleus; Lub ndlwg ntawm electrons nyob rau hauv ib tug neeg xyuas pib tsim hluav taws xob thaum photoelectron yog (physics) ib qho electron electron tawm ntawm qhov chaw ntawm cov khoom los ntawmcov nyhuv photoelectric.
Puas yog photoelectrons electrons?
Thaum lub teeb ci rau ntawm cov hlau, cov khoom siv hluav taws xob tuaj yeem raug tshem tawm ntawm qhov chaw ntawm cov hlau hauv qhov tshwm sim hu ua photoelectric effect. Cov txheej txheem no feem ntau hu ua photoemission, thiab cov electrons uas tau tawm ntawm cov hlauhu ua photoelectrons.
Vim li cas electrons hu ua photoelectrons?
Thaum xws li ib qho hluav taws xob sab hauv raug tshem tawm, siab dua-zog sab nrauv hluav taws xob sai sai poob rau hauv qhov chaw seem. Lub zog dhau los ua rau muaj qhov tso tawm ntawm ib lossis ntau dua electrons los ntawm lub atom, uas yog hu ua Auger effect.
txhais li cas los ntawm photoelectron?
photoelectron. / (ˌfəʊtəʊɪˈlɛktrɒn) / npe. ib qho hluav taws xob tawm ntawm lub atom, molecule, los yog khoom los ntawm qhov xwm txheej photon.
Cov duab hluav taws xob cuam tshuam li cas rau tus qauv atomic?
Cov nyhuv photoelectric kuj lees paub tias hluav taws xob hluav taws xob muaj feem cuam tshuam rau cov qauv atomic ntawm ib lub caij vim tias lub wavelength txiav txim siab pes tsawg electrons raug tso tawm.
