Albert Einstein txoj kev xav ntawm cov nyhuv photoelectric pab txhawb rau De Broglie's Theory thiab yog ib qho pov thawj uas nthwv dej thiab hais tau sib tshooj. Teeb ua tau kuj raug soj ntsuam raws li ib particle lub npe hu ua photon. Yog li, yog tias photon ntawm lub zog ntau dua li ntawm ib qho hluav taws xob hits ib qho khoom uas electron yuav raug tso tawm.
Ua raws li qhov no hauv kev txiav txim siab, yuav ua li cas cov nyhuv photoelectric ua pov thawj tias lub zog yog quantized?
Cov zog ntawm photons ntawm lub teeb yog ua kom muaj nuj nqis raws li E = hv equation. Cov cov nyhuv photoelectric yog ib qho phenomenon uas tshwm sim thaum lub teeb ci mus rau ib tug hlau nto ua rau lub ejection ntawm electrons los ntawm cov hlau. Nws tau pom tias tsuas yog qee qhov frequencies ntawm lub teeb tuaj yeem ua rau ejection ntawm electrons.
Qhov thib ob, koj tuaj yeem ua pov thawj li cas tias lub teeb yog ib qho particle? Cov nyhuv photoelectric tshwm sim thaum lub zog siab photon ( lub teeb particle ) ntaus ib tug hlau nto thiab ib tug electron yog ejected thaum lub photon ploj. Qhov no qhia tau tias teeb tuaj yeem yog a particle THIAB ib nthwv dej. Tsim ib qho kev sim los qhia qhov ntawd lub teeb yog particle , koj tuaj yeem xa mus rau Electron Ob Chav Slit Experiment.
Tsis tas li, yoj particle dual ua haujlwm li cas?
Hauv physics thiab chemistry, yoj - particle duality tuav lub teeb thiab teeb meem pov thawj cov khoom ntawm ob qho tib si nthwv dej thiab ntawm cov khoom . Lub hauv paus ntsiab lus ntawm quantum mechanics, dual hais txog qhov tsis txaus ntawm cov lus pom zoo xws li " particle "thiab" yoj "los piav qhia txog tus cwj pwm ntawm quantum khoom.
Lub teeb zoo li cas ob qho tib si particle thiab nthwv dej?
(Phys.org)- Teeb coj tus cwj pwm ob leeg as a particle thiab as a yoj . Thaum UV teeb hits ib tug hlau nto, nws ua rau ib tug emission ntawm electrons. Albert Einstein piav qhia qhov "photoelectric" cuam tshuam los ntawm kev tawm tswv yim tias teeb - xav tias tsuas yog ib yoj – tseem yog kwj ntawm cov khoom.

Koj ua pov thawj li cas cov kab yog sib npaug hauv cov ntawv pov thawj?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Dab tsi yog cov nyhuv tshuaj ntawm hluav taws xob muab qee qhov piv txwv ntawm cov nyhuv tshuaj?
Ib qho piv txwv ntawm cov tshuaj muaj zog hauv cov hluav taws xob tam sim no yog electroplating. Hauv cov txheej txheem no, muaj cov kua dej uas muaj hluav taws xob dhau mus. qhov no yog ib qho piv txwv ntawm kev siv tshuaj lom neeg hauv hluav taws xob tam sim no
Dab tsi pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?
Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Lub teeb twg siv rau hauv cov nyhuv photoelectric?
Einstein siv lub particle theory ntawm lub teeb los piav txog cov nyhuv photoelectric raws li qhia hauv daim duab hauv qab no. Daim duab 1. Lub teeb tsawg zaus (liab) tsis tuaj yeem ua rau ejection ntawm electrons los ntawm cov hlau nto. Thaum los yog siab tshaj qhov pib zaus (ntsuab) electrons raug rho tawm
Dab tsi yog cov pov thawj hauv Favour of dual Behavior of electron?
Ob qhov xwm txheej ntawm electron tau muab los ntawm de-Broglie thiab ua kom pom tseeb dua los ntawm Bohr. Dub lub cev hluav taws xob thiab cov nyhuv photoelectric qhia qhov zoo li qhov ntawm electron. Electromagnetic hluav taws xob qhia cov nthwv dej zoo li qhov xwm txheej ntawm electron. Ob chav slit sim kuj ua pov thawj ob qhov xwm txheej
