Diffraction, polarization, thiab cuam tshuam pov thawj ntawm yoj xwm ntawm lub teeb ; cov nyhuv photoelectric yog pov thawj ntawm particle xwm ntawm lub teeb.

Ib yam li ntawd, nws tau nug tias, qhov kev sim twg zoo tshaj plaws qhia tau hais tias cov khoom zoo li lub teeb?

Nyob rau hauv niaj hnub physics, ob-slit kev sim yog ib qho kev ua qauv qhia tias teeb thiab teeb meem tuaj yeem pom cov yam ntxwv ntawm ob qho tib si classical txhais tsis tau thiab cov khoom ; Tsis tas li ntawd, nws qhia txog qhov tseem ceeb tshaj plaws xwm ntawm quantum mechanical phenomena.

Tom qab ntawd, lo lus nug yog, yog vim li cas photons ntawm violet lub teeb muaj kev vam meej ntawm dislodging electrons? Qhov twg yog vam meej hauv dislodging electrons los ntawm ib tug hlau nto: photons ntawm violet lub teeb los yog photons ntawm liab teeb ? Violet lub teeb yog vam meej vim lub zog siab dua ntawm a violet photon interacts nrog ib leeg hluav taws xob thiab muab lub zog txaus kom dim ntawm cov hlau.

Ua li no, puas yog cov nyhuv photoelectric ua pov thawj tias lub teeb yog ua los ntawm cov khoom?

Cov cov nyhuv photoelectric txhawb a particle txoj kev xav ntawm teeb nyob rau hauv hais tias nws coj zoo li kev sib tsoo elastic (ib qho uas txuag txhua lub zog) ntawm ob cov khoom , cov photon teeb thiab electron ntawm cov hlau. Txawm li cas los xij ntau hν tshaj lub zog khi yuav yog lub zog kinetic KE ntawm cov hluav taws xob ejected.

Qhov twg hauv qab no tsis txhawb qhov nthwv dej ntawm lub teeb?

Teb: Cov nyhuv photoelectric tsis txhawb qhov nthwv dej ntawm lub teeb.
