Pre-Quantum Electrodynamics

Fundamentals: After properly studying this module, you should be able to:

• give the equations for electric and magnetic fields in terms of the scalar and vector potentials
• give the Lorenz gauge
• give the definition of the d'Alembertian operator
• give the inhomogeneous Maxwell equations (in the language of scalar and vector potentials, in the Lorenz gauge)

Applications: As a strict minimum, you should be able to:

• rederive how gauge transformations look like for scalar and vector potentials
