Document Summary
Wave functions, energy levels and particle in the box. The more wavelengths in the box => higher energy particle. Wave function - describes movement of a particle. Particle in a box - electron between two walls of in nite potential energy // energy is quantized. Psi^2 - probability density // probability of nding the particle in a region. Psi can be both positive or negative // psi^2 will always be positive. Nodes - psi = 0 => psi2 = 0 // no electron found at node // 0% probability // wave functions have n-1 nodes. Hat on h indicates it s an operator. Rydberg equation - discovered by analyzing line spectra. Schrodinger equation - solving particle in a box problem in three dimensions. Bohr model - e- orbited nucleus // energy levels are quantized. Stair and ball analogy - transition one energy to another // no in between. Difference in energy = nal - initial.
