The electroscope - Study guides, Class notes & Summaries

Demonstrating the photoelectric effect with the gold-leaf electroscope - correct answersMETHOD/OBSERVATIONS: -Charged rod is placed on top plate, repelling the gold leaf -When visible light or UV light is shone on a positively charged plate nothing happens, or if visible light is shone on a negatively charged plate -But if UV light is shone on a negatively charged zinc gold plate the gold leaf falls ANALYSIS: -The metal plate loses its negative charge through emission of electrons (not...
