PHYS201 Wave MechanicsSemester 1 2009J D C5C357 Ext 8913 Semester 1 2009 PHYS201 Wave Mechanics1 / 86 Quantum Mechanics and Wave Mechanics IQuantum Mechanics arose out of the need to provide explanations for a range ofphysical phenomena that could not be accounted for by classical physics:Black body spectrumSpectra of the elementsphotoelectric effectSpecific heat of solids ..Through the work of Planck, Einstein and others, the idea arose that electromagneticand other forms of energy could be exchanged only in definite quantities (quanta)And through the work of De Broglie the idea arose that matter could exhibit wave was Einstein who proposed that waves (light) could behave like particles (photons).
The electron in a hydrogen atom should spiral into the nucleus in about 1012 sec. Bohr proposed existence of stable orbits (stationary states) of radius r such that angular momentum =pr n h 2ˇ;1 2 3;::: Leads to orbits of radii rn and energies En: rn = n2 0h2 ˇe2m e En = 1 n2 mee4 8 2 0h 2 n = 1;2;::: Semester 1 2009 PHYS201 Wave Mechanics 7 / 86
