This course is a calculus-based introduction to E&M (electricity and magnetism), waves, and optics. Topics include Coulomb's law (static electric forces), electric and magnetic fields, electric potentials and potential energy, Maxwell's equations, waves, sound, light, image formation, and diffraction. Some basic electrical circuits will be discussed, but we mostly leave this to electrical engineering courses. Here we want to emphasize the theory and concepts inherent in all electric and magnetic phenomena. This is a challenging course in that you must continue applying what you learned in PHYS 2311 (Mechanics and Thermodynamics) and your calculus courses.
A tentative calendar of topics is outlined below.
You should have passed PHYS 2311 with a minimum Grade of D. This means you also have passed Calculus I.
The lab for this class is Physics 2351. There is 1 section on Thursday at noon. Labs will meet in Meyer 122. Your performance in the lab has no direct effect on your grade in the lecture, however, you will learn the PHYS 2321 material better if you work hard in the lab. You will have an informational meeting with your instructor on the first week where you will be assigned your first lab.
||Homework, attendance|| 25%
||Quizzes (drop lowest score)|| 25%
|Exams||There will be two exams and a final.|| 50%
Your final letter grade is calculated roughly as follows:
I will not grade any "harder" than the above. However, if the class mean drops below 75, I will grade more leniently.

Other Course Policies
Attendance will be checked on many days, particularly during the first few weeks. Attendance is crucial on test days or due dates. It is also important for participation in class activities and simply hearing lectures. Let me know in advance (e-mail is good) if you think you will need to miss class. If you miss a quiz or exam because of an unforeseen emergency, let me know as soon as possible, and provide proof of the emergency. The name and phone number of a relevant authority figure (perhaps a parent) can be provided as proof.
Homework will consist of reading and working problems from the textbook or the instructor. Problem solving is a major part of physics and you need practice. Homework turned in after the time it is due will be given 50% credit. It will be scored on completeness and correctness, but not every problem will be checked. You can discuss homework with your classmates, but don't copy their work verbatim. Don't copy the solutions manual verbatim. Show your work, don't just write down the final answer. After a warning, you'll be docked points. Look for keys posted after the homework is due.
Turning in Homework You must turn in hardcopies of your homework. Please write neatly, circle or box final answers, don't put more than one answer on a given row, and put spaces between problems. Engineering paper works well. Don't use spiral notebooks unless you remove the frills from each page.
Practice Quizzes / Self tests will be made available online for each chapter or week of material. (See "Self Tests" below.) These are multiple choice questions linked through the class web page (not Moodle). The answers can be seen by clicking "Grade". I do not see your answers and these do not count towards your grade.
Quizzes will usually be given every week or two. I hope to give most quizzes in-class (allowing about 15 minutes)), but some may be on-line (via Moodle) or take-home. If you miss a quiz you cannot make it up unless you had an excusable absence. Sleeping in is not excused. We will try to arrange an in-person make-up at my office (SA 111). If we cannot find a time before the graded quizzes are returned to the other students, then you may have to take a 0. (For this reason, I will drop your lowest quiz score.)
Exams will be given roughly every 5 weeks (so that there are 2 plus a final). These will weigh most heavily towards your class grade. The final exam will be comprehensive, but will emphasize the last 3-5 weeks of material. One or more of the exams may be given on Moodle (to save class time). The same make-up rules used for quizzes apply (see above), but the lowest exam score is not dropped.
Disruptions You can ask questions during class, but don't interfere with the learning of the students around you with irrelavent chatter. Also, don't operate cell phones or laptops without my permission during lectures. Try not to arrive late or get up and walk out early (unless you are told to for being disruptive).
Calculators I encourage you to use a calculator in this class. However, you may not use calculators to store information for tests and quizzes. (This includes writing equations on the lid.) Tests and quizzes don't usually require much arithmetic, so the calculator is mostly needed for homework.
Tutoring will be available from the Physics Program and possibly Engineering. Listen for announcements in class. (Physics tutoring is usually Thursdays 7-9 pm.) Of course, you are welcome to drop by during my office hours!
Cheating During quizzes and exams it is important that you do your own work without help from others in the class. Getting help from or providing help to others during tests is considered cheating. For homework, you can work together, but if it becomes obvious that you are copying verbatim from a manual or another person, you risk repercussions. I reserve the right to give a 0 score and report students for disciplinary action if I observe cheating. You will usually receive a warning before severe penalties. Other penalties include arbitrary point deductions and excluding the score from your average. During in-class tests, you may not obtain information from electronic devices. If online tests are given, you will be expected to work alone unless explicitly stated otherwise. You will sometimes be allowed to use notes or other aids but you are not to exchange any information with others, including someone not in your class.Common syllabus information.
