Photoelectric Experiment

Postby janessadai 1F » Tue Oct 09, 2018 3:15 pm

What happens to the electrons that are displaced during the experiment? Does the metal end up with a slight positive charge?

The displaced electrons flow through a connection from the detector back into the metal. During the lecture Dr. Lavelle showed the detector therefore maintaining a slight positive charge.

After an electron is ejected from the metal, they will gravitate towards the detector because the detector has a slightly positive charge and the election has a negative charge. The detector is also connected to the metal, allowing the electron to make its way back to the metal. I assume the loss of the electron creates some instability within the metal (a slightly positive charge) that will attract the electron back in order to return to a stable state.
