Gasiorowicz, Chap. 1
PHYS 385 assumes that the student has completed a 67 week introduction to quantum
concepts at the second year level and is currently enrolled in a first course on
differential equations.
The lectures follow the recommended text for much of the
course, and an attempt is made to keep the notation consistent with it.

Introduction
Second year courses on modern physics introduce the idea that the energy of a photon
with frequency
is quantized as
E
=
h
(1)
where
h
= Planck's constant = 6.63 x 10
34
Js.

This proposal explained two physical phenomena that had challenged physicists at the
end of the nineteen century:
•
the frequency distribution of electromagnetic radiation in equilibrium at a fixed
temperature
•
the photoelectric effect.
The role of quantized energy in explaining these phenomena is described in all
introductory texts on quantum mechanics, and will not be discussed further here.
Rather, our starting point is the "old" quantum theory of Bohr and de Broglie, that made
