This is a sample test question I've encountered twice in some practice chemistry finals. I'm a little bit confused about what it's asking.
You are conducting an experiment on the photoelectric effect, and observe that, at a certain frequency and intensity of light, no current flows. According to classical physics, what should you do to make current flow between the electrodes?
According to the Planck equation, $E=h\nu$, says that if I want electrons to escape from one electrode to the other, I need to hit it with a specific frequency. Is that correct? And is that the classical interpretation of the photoelectric effect? How would you phrase the answer to the question, in 3 sentences or fewer? Thanks!
