Keeb Kwm teb: Dab tsi yog qhov pov thawj uas teeb kuj yog ib yoj ? Nws yog vim tej yam hu ua tus Kev sim ob npaug. Yeej, thaum photons raug tua los ntawm ib qho slit thiab lawv ntaus lub detector, lawv ua ib tug qauv ntawm ib tug kab nyob qhov twg. tus slit yog.
Hauv qhov no, dab tsi ua pov thawj tias lub teeb yog nthwv dej?
Cov phenomenon xws li diffraction, reflection, refraction, polarization thiab lwm yam yog cov pov thawj ntawm yoj txoj kev xav ntawm teeb . Whereas photoelectric effect yog ib qho pov thawj ntawm qhov xwm txheej ntawm teeb . Teeb txav hauv nthwv dej , zoo li suab.
Kuj Paub, dab tsi ua pov thawj 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. Thaum zaus ntawm teeb nce, qhov ceev ntawm electron raug ejected nce.
Kuj Paub, yog lub teeb nthwv dej lossis ib qho 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.
Lub teeb yog dab tsi?
Maxwell piav qhia teeb ua ib yam tshwj xeeb heev yoj - ib qho ntawm cov hluav taws xob thiab cov hlau nplaum. Cov teb vibrate ntawm txoj cai kaum rau cov kev taw qhia ntawm kev txav ntawm lub yoj , thiab ntawm txoj cai kaum rau ib leeg. Vim teeb muaj ob qho tib si hluav taws xob thiab sib nqus teb, nws tseem hu ua electromagnetic hluav taws xob.

Vim li cas cov nthwv dej transverse tsim los ntawm av qeeg hu ua cov nthwv dej thib ob?
Secondary waves (S-waves) yog shear waves uas yog transverse nyob rau hauv cov xwm. Tom qab muaj xwm txheej av qeeg, S-nthwv dej tuaj txog ntawm cov chaw nres tsheb seismograph tom qab nrawm dua-tsav P-nthwv dej thiab hloov chaw hauv av perpendicular mus rau kev taw qhia ntawm kev nthuav tawm
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 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
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 lub hlau nto thiab cov hluav taws xob tawm thaum lub photon ploj. Qhov no qhia tau hais tias lub teeb tuaj yeem ua ib qho thiab nthwv dej. Txhawm rau tsim qhov kev sim los qhia tias lub teeb yog ib qho, koj tuaj yeem xa mus rau Electron Ob Chav Slit Experiment
Qhov ntsuas ntsuas twg ntsuas qhov loj lossis lub zog ntawm av qeeg raws li seismic nthwv dej?
2. Richter scale- yog qhov ntsuas ntawm qhov av qeeg qhov loj raws li qhov loj ntawm qhov av qeeg qhov seismic nthwv dej thiab kev txav mus los. Lub seismic nthwv dej yog ntsuas los ntawm seismograph
