Unformatted text preview: reate the observed 'data', some energy (wave) state of the observed object has to be altered. • Taking observations has discrete effects on what we measure. i.e. We change the experiment by observing it! ψ or WAVEfunction obtained from quantum mechanical oscillators as applied to electrons behaving as waves Gives you ENERGY or “Eigenvalue” as a function of the 4 quantum numbers Development of Quantum Mechanical Model: Matrix Mechanics and the Probability Amplitude • Max Born and Werner Heisenberg (and student Pascual Jordan) set-up the basis of the Matrix Mechanics solution of Atomic model Nobel Prize, Physics 1954 Max Born (1928) described, through principles of matrices, that the square of the quantum wave equation Ψ or Ψ2 could be used to predict the probability of where the particle would be found. Probability amplitude is a complex number whose modulus squared represents a probability or probability density. For example, the values taken by a normalised wave function ψ are amplitudes, since |ψ(x)|2 gives the probability density at position x 5 1/21/2014 ψ2 The Quantum Mechanical Picture of the Atom The SQUARE of the WAVEFUNCTION gives you the PROBABILITY of finding the particle relative to...
