Qhov no tau los ua lub npe hu ua photoelectric effect, thiab nws yuav nkag siab hauv xyoo 1905 los ntawm tus kws tshawb fawb hluas hu ua Albert Einstein.
Leej twg pom cov nyhuv photoelectric Einstein lossis Hertz?
Einstein piav qhia txog cov nyhuv photoelectric los ntawm kev qhia txog cov tswv yim quantum thaum ntxov, tab sis Heinrich Hertz nrhiav pom cov nyhuv hauv cov hlau sim hauv xyoo 1887.
Einstein nrhiav pom cov nyhuv photoelectric li cas?
Nws pom tias qhov siab tshaj plaws hluav taws xob kinetic zog yog txiav txim siab los ntawm qhov zaus ntawm lub teeb… quantized pob ntawv los piav qhia cov ntaub ntawv sim los ntawm cov nyhuv photoelectric.
Einstein txoj kev xav ntawm cov nyhuv photoelectric yog dab tsi?
Einstein qhov kev piav qhia ntawm cov nyhuv photoelectric yog qhov yooj yim heev. Nws xav tias lub zog kinetic ntawm cov hluav taws xob ejected yog sib npaug ntawm lub zog ntawm qhov xwm txheej photon rho tawm lub zog yuav tsum tau tshem tawm cov khoom siv hluav taws xob, uas yog hu ua kev ua haujlwm.
Puas yog lub teeb nthwv dej lossis ib feem?
Lub teeb tseem yog ib qho ! Einstein ntseeg tias lub teeb yog ib qho (photon) thiab ntws ntawm photons yog nthwv dej. Lub ntsiab lus tseem ceeb ntawm Einstein lub teeb quantum txoj kev xav yog tias lub teeb lub zog cuam tshuam nrog nws cov zaus oscillation.

Leej twg nrhiav tau txoj cai ntawm photoelectric nyhuv?
Qhov no tau los ua lub npe hu ua photoelectric effect, thiab nws yuav nkag siab hauv xyoo 1905 los ntawm tus kws tshawb fawb hluas hu ua Albert Einstein . Yuav ua li cas yog thawj txoj cai ntawm photoelectric nyhuv? Peb txoj cai ntawm cov nyhuv photoelectric yog raws li hauv qab no;
Rau cov nyhuv photoelectric v?
Thaum lub teeb tawm tsam cov ntaub ntawv, nws tuaj yeem tso cov hluav taws xob tawm ntawm lawv. Qhov no yog hu ua cov nyhuv photoelectric, txhais tau hais tias lub teeb (duab) tsim hluav taws xob. … Qhov hluav taws xob uas nres cov electrons kom tsis txhob ncav cuag cov hlau sib npaug lub zog hauv eV Piv txwv li, yog -3.
Leej twg thawj zaug pom cov nyhuv photoelectric?
Qhov no tau los ua lub npe hu ua photoelectric effect, thiab nws yuav nkag siab hauv xyoo 1905 los ntawm tus kws tshawb fawb hluas hu ua Albert Einstein . Leej twg tshawb nrhiav cov nyhuv photoelectric? Nobel nqi zog hauv Physics 1921 tau muab tsub rau Albert Einstein"
Leej twg tsim cov nyhuv stroboscopic?
Lub tshuab hluav taws xob strobe lub teeb stroboscope tau tsim nyob rau xyoo 1931, thaum Harold Eugene Edgerton("Doc" Edgerton) ua haujlwm lub teeb nyem los kawm lub tshuab ua haujlwm . Dab tsi yog cov nyhuv stroboscopic? Cov nyhuv stroboscopic yog qhov pom tshwm sim tshwm sim los ntawm kev siv lub npeuas tshwm sim thaum tsis tu ncua kev sib hloov lossis lwm yam kev txav mus los yog sawv cev los ntawm cov qauv luv luv lossis tam sim no (raws li kev tawm ts
Leej twg tsim cov nyhuv schlieren?
Onlyabouta kaum xyoo tom qabHooke txoj haujlwm, Christiaan Huygens (1629-1695) kuj tau tsim ib qho qauv ntawm cov txheej txheem schlieren siv thaj tsam nyob deb-tsaus [26]. Huygens tam sim no nto moo, tau kawg, rau nws qhov kev tshawb pom hnub qub, ntsuas lub sij hawm, kinetic zog mis, thiab lub ntsiab lus tseem ceeb kho qhov muag hu ua nws (Sect .
