321 Quantum MechanicsUnit 2 So far… Matter behaves like waves (photoelectric effect, Compton, de Broglie etc) 1D Schrödinger equation Physically acceptable solutions only possible for certain discrete values of the energy Energy level spacing qualitatively similar to atoms Predicted tunnelling / interference – seen experimentally quantumphysics.iop/org Unit 2 Move from 1D to 3D to obtain quantitative predictions
