Nyob rau hauv physics thiab chemistry, nthwv dej-particle dual tuav lub teeb thiab teeb meem nthuav tawm cov khoom ntawm ob nthwv dej thiab cov khoom. Lub ntsiab lus tseem ceeb ntawm quantum mechanics, duality hais txog qhov tsis txaus ntawm cov ntsiab lus zoo li "particle" thiab "yoj" los piav qhia txog tus cwj pwm ntawm quantum khoom.
Vim li cas yoj-particle dual muaj nyob?
Raws li txoj hlua txoj kev xav yoj particle dual muaj tshwm sim vim tias cov hluav taws xob tau sawv nthwv dej, yog li cov hluav taws xob tuaj yeem ua tsis tau.
Vim li cas lub teeb ob qhov particle thiab nthwv dej?
Quantum mechanics qhia peb tias teeb tuaj yeem coj mus ua ib ntuslossis nthwv dej. … Thaum UV lub teeb tsoo lub hlau nto, nws ua rau muaj hluav taws xob emissions. Albert Einstein piav qhia qhov "photoelectric" cuam tshuam los ntawm kev tawm tswv yim tias lub teeb - xav tias tsuas yog nthwv dej - kuj yog cov kwj deg.
Yuav ua li cas yoj ua tau ib yam?
Ntsuag yog qhov tshwm sim txawv heev hauv peb lub ntiaj teb, raws li yog cov khoom. Thiab peb muaj cov lej sib txawv los piav txog lawv txhua tus. … Thaum nws los txog rau tej yam xws li photons thiab electrons, cov lus teb rau lo lus nug "Puas lawv coj zoo li nthwv dej los yog hais?" yog… yog.
Is Heisenberg Uncertainty Principple?
txoj ntsiab cai tsis meej, tseem hu ua Heisenberg uncertainty hauv paus ntsiab lus lossis indeterminacy txoj cai, nqe lus, hais lus (1927) los ntawm Germanphysicist Werner Heisenberg, uas txoj haujlwm thiab qhov nrawm ntawm ib qho khoom tsis tuaj yeem ntsuas tau raws nraim, tib lub sijhawm, txawm tias hauv kev xav.

Rau qhov electromagnetic yoj poynting vector yog sawv cev los ntawm?
Poynting vector S yog txhais tias yuav sib npaug rau cov khoom hla (1/μ)E × B, qhov twg μ yog qhov permeability ntawm nruab nrab los ntawm cov hluav taws xob dhau mus. (saib magnetic permeability), E yog qhov amplitude ntawm hluav taws xob teb, thiab B yog qhov amplitude ntawm magnetic teb.
Yuav ua li cas thiaj nrhiav tau qhov zaus ntawm sine yoj?
Qhov sib npaug ntawm qhov kev ua haujlwm sine yog f(x)=sinx. Hauv qhov no b, zaus, sib npaug rau 1 uas txhais tau tias ib lub voj voog tshwm sim hauv 2π. Dab tsi yog qhov zaus ntawm sine yoj? Qhov zaus ntawm sine yoj yog tus naj npawb ntawm cov voj voog tiav uas tshwm sim txhua ob.
Yuav ua li cas yog ib tug sheave li coj yoj?
Nplooj nplej yog cov neeg ua liaj ua teb zoo siab. Thaum bundled nyob rau hauv tuab, siab pawg, ib tug sheaf yog ib tug lub cev sau ntawm siab nplej uas tau muab khi thiab npaj rau kev ua ntxiv. Ib tug sheave kuj yog ib lub pulley uas tuaj yeem nqa tau ntau qhov hnyav tshaj qhov chaw loj thaum ua ke nrog ntau lub laub tshuab.
Vim li cas ho tsis muaj dual wielding halo?
Dual wielding, raws li tus neeg ua si nkag mus tau, raug tshem tawm hauv Halo 3: ODST, Halo: Reach, Halo 4, thiab Halo 5. Hais txog Halo: ncav, qhov kev tshem tawm yog vim riam phom tshiab sandboxuas tsis tuaj yeem txhawb nqa tag nrho gameplay tsim.
Puas protons muaj yoj particle dual?
Raws li quantum txoj kev xav tau tsim, nws tau pom tias yuav tsum tsis yog photons nkaus xwb, tab sis electrons thiab protons - tag nrho cov teeb meem - muaj nthwv dej-particle duality. Yuav ua li cas hais muaj nthwv dej-particle dual?
