Objectives and Homework for September 28, 2004.
[1] Understand the results and implications of the Franck-Hertz experiment.
[2] Be able to explain how Davisson & Germer confirmed DeBroglie's hypothesis.
[3] Understand the mathematics of waves.
[4] Understand what a Fourier Transform is.
[5] Understand the concepts "dispersive medium", "phase velocity", and "group velocity".
[6] Understand the "standard deviation" definition of ?Q, where Q is some variable.
[7] Know what the product ?x?px is for a Gaussian wave packet, and realize that this is its minimum possible value. Hence understand the derivation of the Heisenberg Uncertainty relation between x and px.
[8] Realize that there is no uncertainty relation between variables such as x and py , etc., and realize why.
[9] Know the Heisenberg uncertainty relation between E and t.
[10] Understand the probability interpretation for the wavefunction. Know also how the quantum mechanical wavefunction is similar to the classical electric and magnetic fields, and know how they are different.
[11] Understand what is meant by the term "normalization", and be able to normalize a wavefunction.
