## Course Description

In this course we will cover the following basic topics:

• Electrostatics. Charge, electric force, electric field and Coulomb's law, Gauss's law, electric potential. Capacitance and dielectrics.

• Magnetostatics. Current, magnetic force, magnetic field and the Biot-Savart law, Ampere's law. Magnetic moments, torque, magnetic precession. Magnetic materials (diamagnetism, paramagnetism, ferromagnetism).

• Electromagnetic Induction. Motional EMF, induced voltage, Faraday's law, Lenz's law. Mutual and self inductance. Generators.

• Elementary circuits (DC and AC). Kirchoff's rules. Ohm's law. Time-varying potentials, RC, LR, LRC circuits. High pass, low pass, band pass filters, and Q.

• The Maxwell displacement current and its connection to charge conservation. Maxwell's equations. The electromagnetic wave equation and light. Energy density, the Poynting vector, radiation pressure.

• Properties of light. Snell's law, simple polarization (absorption, scattering, reflection), Huygen's principle, dispersion, the spectrum. Geometric optics and ray diagrams: mirrors, lenses, the eye, optical instruments. Physical (wave) optics: thin film interference, 2,3,4...N slit interference, single slit diffraction, diffraction gratings.

There will be, as you may have guessed, lots of homework problems. Homework is an essential part of learning physics and must not be neglected. I expect all students to do the assigned problems and keep up with the reading. The structure and organization of the course will be (approximately!):
