Qhov no tau paub tias yog cov nyhuv photoelectric, thiab nws yuav nkag siab hauv xyoo 1905 los ntawm tus kws tshawb fawb hluas hu ua Albert Einstein. Einstein txoj kev txaus siab rau kev tshawb fawb tau pib thaum nws muaj 4 lossis 5 xyoos, thiab thawj zaug pom lub tshuab sib nqus.
Leej twg ua kom pom cov nyhuv photoelectric sim ua ntej?
Qhov tshwm sim tau pom thawj zaug los ntawm Heinrich Hertz hauv 1880 thiab piav qhia los ntawm Albert Einstein hauv 1905 siv Max Planck's quantum theory of light. Raws li thawj qhov kev sim uas pom tau hais tias quantum txoj kev xav ntawm qib zog, kev sim photoelectric effect yog qhov tseem ceeb hauv keeb kwm.
Leej twg yog lub luag haujlwm rau cov nyhuv photoelectric?
Credit rau qhov kev tshawb pom ntawm cov duab hluav taws xob tau muab rau Heinrich Hertz, uas xyoo 1887 pom tias hluav taws xob hla ntawm ob lub spheres yuav tshwm sim yooj yim dua, yog tias nws txoj hauv kev tau illuminated nrog lub teeb los ntawm lwm yam hluav taws xob tawm.
Cov nyhuv photoelectric siv li cas niaj hnub no?
Tus so ntawm photon lub zog hloov mus rau tus nqi tsis zoo, hu ua photoelectron. To taub yuav ua li cas qhov no ua hauj lwm revolutionized niaj hnub physics. Daim ntawv thov ntawm cov nyhuv photoelectric coj peb "lub qhov muag hluav taws xob" qhov rooj qhib, lub teeb ntsuas siv hauv kev yees duab, hnub ci vaj huam sib luag thiab kev luam theej duab.
Vim li cas cov nyhuv photoelectric tshwm sim?
Cov nyhuv photoelectric yog qhov tshwm simuas tshwm sim thaum lub teeb ci rau ntawm qhov chaw hlau ua rau ejection ntawm electrons los ntawm cov hlau ntawd. … Tsawg zaus lub teeb (liab) tsis muaj peev xwm ua rau ejection ntawm electrons los ntawm cov hlau nto. Thaum los yog siab dua qhov pib zaus (ntsuab) electrons raug ejected.

Vim li cas qhov pib zaus yog qhov tsim nyog rau cov nyhuv photoelectric?
Cov nyhuv photoelectric yog ib qho tshwm sim uas tshwm sim thaum lub teeb ci rau ntawm qhov chaw hlau ua rau cov hluav taws xob tawm ntawm cov hlau ntawd. … Qhov tsawg kawg nkaus zaus uas yuav tsum tau ua rau electron ejection yog hu ua qhov pib zaus.
Leej twg piav qhia qhov tshwm sim ntawm cov nyhuv photoelectric?
Einstein thaum kawg tau muab khoom plig Nobel rau Physics hauv xyoo 1921 rau kev piav qhia txog cov nyhuv photoelectric. Leej twg 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.
Puas tsis yog hlau qhia cov nyhuv photoelectric?
Kev piav qhia: Cov nyhuv Photoelectric tsuas yog rau thawj pab pawg txawm tias tsis yog tag nrho cov ntsiab lus.Yog li nws tsis pom los ntawm cov hlau tsis yog hlau kuj . Nyob rau hauv cov nyhuv no valence electrons ejected los ntawm photometal thaum lub teeb yog absorbed los ntawm cov hlau.
Leej twg txoj cai piav qhia txog kev solubility ntawm cov roj hauv cov tshuaj?
Henry Txoj Cai: Lub solubility ntawm cov pa hauv cov kua yog ncaj qha proportional rau ib nrab siab ntawm cov pa saum cov kua. Leej twg piav qhia txog kev solubility ntawm cov roj hauv cov tshuaj? Henry Txoj Cai hais tias: Lub solubility ntawm cov roj hauv cov kua yog ncaj qha proportional rau lub siab ntawm cov roj ntawd saum npoo ntawm cov tshuaj.
Qhov kev piav qhia piav qhia txog lub cev tsis muaj zog ntawm tes?
Cov ntsiab lus hauv cov txheej txheem no (10) Cov lus piav qhia twg piav qhia qhov tsis muaj zog, xov paj hlwb? Nyuaj rau palpate, yuav ploj mus thiab tawm, yooj yim obliterated. Thaum piav qhia txog qhov tsis muaj zog ntawm tes tus kws saib xyuas neeg mob yuav tsum sau cov lus nug?
