Physics 751: Midterm I Study Guide 2008
You should carefully
read through all the notes I’ve posted on the web.
I will ask no questions on the historical stuff at the beginning,
except for the purely physics content
.
For
example, you should have a good understanding of the Bohr atom, including the classical limit of a very
large atom and how that fixes the quantum of angular momentum, and know how the Uncertainty
Principle can be used to estimate the size of bound states, such as the atom on the table.
You should be sure you can do
all
the problems that were assigned for homeworks 14.
You should know Schrödinger’s equation by heart, the probability interpretation of the wavefunction,
the conservation of probability current, and the expectation value of an operator.
Be able to find the timedependent probability and current distribution for a superposition of states of
different energies.
Know the definition of the delta function as a limit of a Gaussian wavepacket, and be able to Fourier
transform a Gaussian wavepacket. (Know the integral you need by heart.)
