    Try the 2nd paragraph of the article, and section 3 on Historical Development. You can also follow some of the suggested reading out of the article to get more details on the experiments.

    Those are good choices. Was there anything special about the photoelectric effect work? Who did those experiments? Did anything special happen to that scientist as a result of the experiments?
