Outline Photoelectric effect o E: ν relationship Wave-particle duality of light Wave nature of matter Atomic spectrum of hydrogen and what we learned from it Photoelectric Effect: What can we vary? What can we measure? Does the frequency of light affect the number of electrons popped off the metal surface? (Intensity held constant) Does the intensity of light affect the K.E. of electrons ejected from surface? Does the frequency of light affect the kinetic energy of the released electrons? (Intensity held constant) (Graph updated) Does the intensity of light affect the number of electrons ejected from surface? Intensity of light is NOT related to the __________of its photons. Intensity is related to the _________ of photons.
