Kev piav qhia: Cov nyhuv Photoelectric tsuas yog rau thawj pab pawg txawm tias tsis yog tag nrho cov ntsiab lus. Yog li nws tsis pom los ntawm cov hlau tsis yog hlau kuj . Nyob rau hauv cov nyhuv no valence electrons ejected los ntawm photometal thaum lub teeb yog absorbed los ntawm cov hlau. Cov hlau tsuas yog qhia qhov dawb valance electrons valance electrons Lub plhaub valence yog txheej ntawm orbitals uas muaj zog nkag tau rau kev txais cov khoom siv hluav taws xob los ua cov ntawv cog lus tshuaj. Rau cov ntsiab lus tseem ceeb, lub plhaub valence muaj cov ns thiab np orbitals hauv lub plhaub sab nraud. https://en.wikipedia.org › wiki › Valence_electron

Puas photoelectric effect ua haujlwm ntawm cov hlau tsis yog hlau?
Cov nyhuv photoelectric tshwm sim ntau zaus. nrog atoms tuav lawv cov electrons nruj nreem. photon tsis tshua muaj feem cuam tshuam rau qhov tsis muaj hluav taws xob. … Photoelectric effect tseem tuaj yeem tshwm sim hauv cov hlau tsis yog hlau tab sis nws yooj yim dua los ua rau hlau.
Puas tag nrho cov hlau puas muaj cov nyhuv photoelectric?
Kev soj ntsuam ntawm kev siv hluav taws xob hluav taws xob. Txawm hais tias photoemission tuaj yeem tshwm sim los ntawm cov khoom siv, nws tau yooj yim pom los ntawm cov hlau thiab lwm yam khoom siv.
Qhov twg tsis pom cov nyhuv photoelectric?
Alkali hlau (tshwj tsis yog Li) nthuav tawm cov nyhuv photoelectric. Lub peev xwm los nthuav tawm cov nyhuv photoelectric yog vim qhov tsis muaj nqi ntawm ionizationlub zog ntawm alkali hlau. Lithium tsis emit photoelectrons vim muaj nuj nqis ntawm ionization zog.
Yuav ua li cas hom hlau pom cov nyhuv photoelectric?
- Peb pom tias: Li, Na, K thiab Mg muaj nqis qis dua li qhov xwm txheej muaj zog. Yog li, cov hlau no yuav pom cov nyhuv photoelectric. Yog li ntawd, plaub hlau yog qhia cov nyhuv photoelectric.
