Photoelectric effect- how is it detected?

Postby Cowasjee_Sanaea_3E » Thu Sep 29, 2016 5:27 pm

When the photoelectric effect was conducted, or is conducted, how are the electrons (the ones being emitted) being detected or measured? Are they being detected individually? All together? By the amount of kinetic energy they have?

And is their any way that the electrons can be detected visibly (as in light)?

Thanks in advance!

In the photoelectric effect, the electrons are detected by a detector. The electrons will not be detected visibly in the form of light in the photoelectric effect. In atomic spectroscopy, electrons are excited to a higher energy level and when they return back to the original energy level, they emit energy in the form of light. However, in the photoelectric effect, the electron is being removed rather than just being excited.
