E2 Quantum physics [HL only]
Is it a wave...? Is it a particle...? It's light! (And electrons and other things too...) The focus of this activity is on the photoelectric effect, which the wave model of light fails to explain. You will come to understand how Milikan measured photoelectron energy, use a simulation to understand... In this activity you will observe electron diffraction, an effect which can only be explained in terms of probability...
