Kev Xaiv Qhia Tawm Photoelectric effect
Cov yees duab nyhuv tawm yog qhov tseem ceeb thiab zoo nkauj tshwm sim hauv physics. Nyob rau hauv kev tsis sib haum xeeb ntawm lub tshuab hluav taws xob hluav taws xob siab tshaj li ntawm qee qhov zaus (qhov zaus no hu ua qhov ntsuas pib), cov xaim hluav taws xob hauv qee yam khoom nqus tau lub zog thiab khiav tawm los ua qhov tam sim no, uas yog, photoelectricity.
Qhov teeb meem photoelectric tau tshwm sim los ntawm German kws kho lub cev Hertz xyoo 1887, thiab kev txhais cov ntsiab lus raug thov los ntawm Einstein. Hauv cov txheej txheem ntawm kev kawm cov txiaj ntsig photoelectric, cov kws tshawb fawb muaj kev nkag siab tob dua txog cov quantum xwm ntawm photons, uas muaj kev cuam tshuam loj rau lub tswvyim ntawm yoj-particle duality.
