We are shining a red light on a totally different metal, and are ejecting photo electrons with a small KE of 1.5 eV. We are going to make predictions about what happens when we shine light of a greater intensity red light on the same sample. Identify what classical (wave) theory of light incorrectly predicts we would observe. Contrast that with the result which the Quantum Model correctly predicts. I am looking for several solid details.
