Photoelectric Effect Lab
Introduction:
Three fundamental questions of physics are:
1) What is matter?
2) What is energy?
3) What is the nature of the interaction between energy and matter?
These quest

Particle In A Finite Well
We return to solving simple systems that can be used to model real
physical systems like the nucleus.
The first system considered is a particle of energy E in a f

Operators In Quantum Mechanics
A.
Hermitian Adjoint - A +
The Hermitian adjoint of an operator A is the operator A + which obeys
the equation
A + = A
EXAMPLE: Show that the Hermitian adjoi

Time Independent Schrdinger Equation
A.
The first problem that we will consider is the case where the
Hamiltonian is not a function of time. In classical mechanics, the time
derivative of

Louis de Broglie - 1924
All matter ("particles") also posses wave properties.
Louis de Broglie assumes that nature has a basic symmetry. If light travels as a

What is a blackbody?
A blackbody is an object that absorbs all radiation that is incident upon it.
When radiation falls upon an object,
