CHAPTER 3: The Experimental Basis of Quantum Theory
... Classical theory predicts that the total amount of energy in a light wave increases as the light intensity increases. The maximum kinetic energy of the photoelectrons depends on the value of the light frequency f and not on the intensity. The existence of a threshold frequency is completely inexplic ...
