Original Photoelectric Experiment

Postby Nina_A_Section1E » Thu Apr 12, 2018 1:49 pm

What was the photoelectric experiment originally designed to do? I didn't catch this from the lecture or module video, and I'm not really sure

A. Measure how much energy is required to remove an electron from a metal surface.

B. Measure how much energy is required to add an electron to a metal surface.

C. Measure how much free energy is released to remove an electron from a metal surface.

D. Measure how much free energy is released to add an electron to a metal surface.

E. None of the above

I believe the aim was to observe how the transfer of energy from light to an electron in the metal results in the emission of said electron from the metal

I think there through previous experiments it was observed that electrons were emitted from various metals when different energy levels of beams pointed at it and so the photoelectric experiment was to identify why/how that happened. Eventually the discrete levels of energy were discovered.

From what I remember in lecture, it was an experiment where they tried to get an idea if there was enough energy from UV light to remove an electron from the sheet metal. I'm confused about the idea of free energy though.
