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.
