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.
Ib yam li ntawd, koj tuaj yeem nug, puas yog lub teeb nthwv dej lossis cov khoom ua pov thawj koj cov lus teb?
Teeb Tseem yog a Particle ! Tam sim no uas tus dual xwm teeb as "ob a particle thiab a yoj "ua ua pov thawj , nws txoj kev xav tseem ceeb tau hloov zuj zus ntxiv los ntawm electromagnetics rau hauv quantum mechanics. Einstein ntseeg teeb yog a particle (photon) thiab tus ntws ntawm photons yog ib yoj.
Peb yuav ua li cas thiaj paub tias lub teeb yog nthwv dej? Teeb coj li a yoj - Nws undergos reflection, refraction, thiab diffraction ib yam li txhua yam yoj yuav. Txawm li cas los xij tseem muaj ntau qhov laj thawj los ntseeg hauv qhov xwm txheej wavelike teeb.
Kuj paub, cov nyhuv photoelectric ua pov thawj li cas tias lub teeb yog ib qho particle?
Cov cov nyhuv photoelectric txhawb a particle txoj kev xav ntawm teeb nyob rau hauv hais tias nws coj zoo li kev sib tsoo elastic (ib qho uas txuag txhua lub zog) ntawm ob cov khoom , cov photon teeb thiab electron ntawm cov hlau. Qhov tsawg kawg nkaus ntawm lub zog xav tau los tshem tawm cov hluav taws xob yog lub zog khi, BE.
Dab tsi ua pov thawj tias lub teeb yog ib qho particle?
Quantum saib ntawm teeb : Cov nyhuv photoelectric qhia cov pov thawj tias teeb tau nthuav tawm particle cov khoom ntawm quantum nplai ntawm atoms. Tsawg kawg teeb tuaj yeem ua tiav qhov chaw txaus ntawm lub zog kom tshem tawm cov hluav taws xob los ntawm cov hlau nto.

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

Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Koj tuaj yeem ua pov thawj li cas 2 daim duab peb sab zoo sib xws siv lub kaum sab xis sab SAS zoo sib xws postulate?
SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm daim duab peb sab thiab lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces ob daim duab peb sab zoo ib yam. Ib qho kev hloov pauv zoo sib xws yog ib lossis ntau qhov kev hloov pauv tsis tu ncua ua raws li kev dilation
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Dab tsi pov thawj koj tuaj yeem hais txog qhov xwm txheej ntawm lub teeb?
Diffraction, polarization, thiab cuam tshuam yog pov thawj ntawm nthwv dej ntawm lub teeb; Cov nyhuv photoelectric yog pov thawj ntawm qhov xwm txheej ntawm lub teeb
