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"rau nws cov kev pabcuam rau Theoretical Physics, thiab tshwj xeeb tshaj yog rau nws nrhiav pom txoj cai ntawm cov teebmeem photoelectric. "
Yuav ua li cas yog thawj txoj cai ntawm photoelectric nyhuv?
Peb txoj cai ntawm cov nyhuv photoelectric yog raws li hauv qab no; 1) Lub emission ntawm electrons los ntawm qhov chaw nres tom qab ib tug tej zaus hu ua qhov pib zaus2) Tus naj npawb ntawm electrons uas tawm ntawm qhov chaw yog ncaj qha proportional rau qhov siv ntawm qhov teeb meem. teeb.
Einstein ua pov thawj li cas ntawm cov nyhuv photoelectric?
Nyob rau xyoo 1905, Albert Einstein tau luam tawm ib daim ntawv tshaj tawm hypothesis tias lub zog lub teeb yog nqa hauv cov pob khoom sib caislos piav qhia cov ntaub ntawv sim los ntawm cov nyhuv photoelectric. … Ib tug photon saum ib qhov chaw pib muaj lub zog yuav tsum tau tshem tawm ib qho hluav taws xob, tsim kom pom cov nyhuv.
plaub txoj cai ntawm kev siv hluav taws xob yog dab tsi?
Lub sij hawm nkag ntawm qhov teeb meem ntawm lub teeb thiab emission ntawm electron yog nil Qhov zaus ntawm qhov teeb meem ntawm cov khoom txiav txim siab lub zog kinetic ntawm cov hluav taws xob emitted. Tus naj npawb ntawm cov electrons emission thiab qhov siv ntawm lub teeb teeb meem yog proportional rau ib leeg.
