Photoelectric effect gold leaf
Websimple demonstration of photoelectric effect. the gold leaf electroscope. what happens if you place a NEG electrode on the gold leaf electroscope. 1) excess electrons dep on plate & stem of electroscope. 2) this neg charge flows to gold leaf. 3) bc both both stem & leaf now have neg charge, they REPEL leaf lifts away. WebThe gold leaf experiment shows that only light above a certain threshold frequency is able to eject electrons. If the frequency of the light incident on the metal surface is even slightly below this threshold frequency, then no electrons …
