## 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!):

20% of grade Weekly Homework. This will include a Webassign component designed to stimulate reading of the chapter(s) before the associated lectures.
20% Weekly Quizzes
20-30% Hour Exams (3)
20-30% Final
10% Lab
1/3 letter grade Extra Credit Project

Grading Scheme: The final exam can replace any one hour exam grade, provided that it is higher. This allows students to make up for their worst single hour exam performance with their final, so one bad exam day won't hurt your grade. If you get below a 50 (and the curve is otherwise normal) and have not religiously handed in your homework, you fail (F). If you get less than a 60 and have not religiously handed in your homework, you get an D. If you get 60 or more you get a C- or better and ``pass''. If you have religiously done your homework, but have somehow managed to end up less than a 60 or (worse) 50, this will be taken into account and adjustments may be made at my discretion. If you have not consistently done and handed in your homework on time, don't bother me about your grade.

Note that the class performance will be plotted on a histogram and adjustments to the above scheme will be made as required by the distribution. In addition, I reserve the right to make modest changes in the exact percentages I assign to any particular component of the grade - there is some variation from year to year in the amount of homework, the number of quizzes, and the difficulty of the exams. Finally, I reserve the right to adjust your distribution-determined grade (up or down) in consultation with Dr. Mary Creason and the TAs if for any reason we feel that this grade does not correctly reflect your degree of learning.

If you are concerned about your grade, you should come see me early and often; extra credit can be obtained a variety of ways to help avoid a bad grade or to augment a good one. However, it is too late to do much about this in mid-April!
