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.
Dab tsi yog qhov tseem ceeb ntawm qhov pib zaus?
Qhov chaw pib ntawm cov hlau yog hais txog qhov zaus ntawm lub teeb uas yuav ua rau lub tshuab hluav taws xob tawm ntawm cov hlau ntawd. … Lub teeb ntawm qhov pib zaus yuav tshem tawm cov hluav taws xob uas tsis muaj zog kinetic. Lub teeb saum toj ntawm qhov pib zaus yuav eject ib qho hluav taws xob nrog qee lub zog kinetic.
Dab tsi yog qhov pib zaus rau cov nyhuv photoelectric?
Lub photoelectric pib zaus, cim los ntawm Greek tsab ntawv nu nrog subscript zero, ν 0 , yog qhov zaus ntawm qhov cuam tshuam NW nyuam qhuav ua tau; Nws yog muab los ntawm qhov piv ntawm kev ua haujlwm ua cim los ntawm Greek tsab ntawv psi, ψ, rau Planck qhov tas li (ν0=…
qhov pib zaus thiab kev ua haujlwm yog dab tsi hauv cov nyhuv photoelectric?
Threshold Frequency: Qhov pib zaus yog qhov tsawg zaus ntawm lub teeb hauv qab uas cov photoelectrons tsis tawm. Ua haujlwm muaj nuj nqi: Lub zog tsawg tshaj plaws uas tuaj yeem tso cov hluav taws xob tawm ntawm qhov chaw ntawm cov hlau.
zaus cuam tshuam li cas rau cov nyhuv photoelectric?
Nyob rau hauv cov nyhuv photoelectric, electrons raug ejected los ntawm ib tug hlau phaj thaum ntaus los ntawm photons ntawm electromagnetic hluav taws xob. … Qhov luv luv wavelength (qhov ntau dua), lub zog ntawm photon ntau dua.
