We discussed this in class today, but I'm still unsure of the reason why plastic can't be used for the experiment. Is it because the experimental setup requires a conductive material, or is it because plastics (and other non-conductive materials) don't emit photons? thanks
Hi! The experiment requires a conductive material (metal), and since plastics and other materials are not conductive, the experiment wouldn't work with the use of a non-metal surface. Hope this clarifies things for you!
The Professor said that the material must be able to conduct electricity and if not and electron will not be emitted after shining photons onto the object. Plastics are unable to act as conductors and thus the experiment would be unable to work.
