Mathematical representation of 1D plane waves; wavefunction, amplitude, frequency, wavelength, wavenumber, speed, energy, intensity and impedance. The Doppler effect. Superposition; standing waves, beats, interference. Phase and group velocity; dispersive and non-dispersive media. Complex exponential notation. Mechanical impedance. Reflection and transmission at boundaries.
Quantum mechanics in 1D (15 lecture hours): Motivation: evidence for QM, Planck's quantum hypothesis, wave-particle duality, de Broglie & Planck-Einstein relations, uncertainty principle. Wave mechanics: Wave functions, probability density and normalisation. Observables; position, momentum and energy. Schrödinger's equation; time dependence of the wavefunction, stationary states, superposition and measurement, time-independent Schrödinger equation. Motion in one dimension: Eigenfunctions of the infinite square well, parity of solutions, superposition states. Dirac notation. Bound states of the finite square well. Motion of free particles. Reflection and transmission at a step. Tunnelling through a barrier. The harmonic oscillator.
