Reading through the lecture notes, I had a weird idea which came in the form of an experiment that could be done.
Imagine you shine light through two slits. Obviously you will get an interference pattern with bright and dark lines (constructive and destructive interference). Then on the other side of the slit, you have a shiny metal surface where you view the interference pattern. Not sure about this but would you be able to see an interference pattern on a shiny metal surface? The question is if you could, would you still be able to say that the particle theory of light (photoelectric effect), which states that light is composed of individual packets called photons which each carry a certain energy E= hf, holds true?
When you try and detect the current flowing through the metal, i am guessing that current still flows otherwise by now quantum theory would be in a big mess haha. But I fail to understand how they could get out of this experiment. Anyone care to explain?
Cheers
