Physics 262                                  (as of May 10, 2006)


General information
The course covers three major areas of physics: electromagnetic waves and optics, special relativity, and quantum physics. We will follow the course schedule listed below. Your input, in terms of questions and comments will help determine our pace, so that it may be updated from time to time.

Time and place: MWF 12:00-12:50PM, Regener Hall 103
Instructor: Prof. Y. Pihlström
Office hours: Wednesdays 10:00-11:30AM in Regener 114. Other times by appointment. To contact me outside class, email is the best choice ylva@unm.edu, or phone to my office (277-4492, P&A 170).
Textbooks: Fundamentals of Physics, Halliday, Resnick and Walker, 6th Edition.
Special Relativity: A Modern Introduction, H.C. Ohanian
Exams: There will be four exams, out of which three are sectional. These will take place during regular class hours. The fourth is a final comprehensive (on all course material), and is given Friday May 12, 10:00AM-12:00PM in Regener 103. The three exams with the best scores will account for 75% of your final grade. In general, make-up exams will NOT be given unless you have a very valid reason, and make-ups will be oral. NO make-ups will be given unless arranged before the exam.
Exam dates: Mid-terms: February 24, April 3 and May 5 (during regular class); Final: Friday May 12 (10:00AM-12:00PM). NOTE: you can start at 9AM, see below.
FINALI will start handing out the final exam at 9AM in RH 103, Friday May 12. We got one more hour test time, and the test is scheduled for 9AM-12PM on Friday. If you want to get your exam returned, and/or discuss your final grade, you can come to my office between 9AM-2PM on Monday May 15.
Homework: Homework will account for 25% of your final grade. Each week you will be given one set of written problems (HW; posted on WebCT on Wednesdays, due the following Wednesday), and one WebAssign homework (WA; posted on WebAssign on Mondays, due Friday same week). A late homework will not give full points, and homework handed in later than one week will not be accepted at all.

Note on WebAssign: You do need to purchase a WebAssign card at the Bookstore and that will give you your access code. Please do this before Feb 1. For WebAssign, the user name is the first part of your email address, the school code is "unm" and the password is the 4 last digits of your SS (omit leading zeros).

WebCT: The username is your UNM NetID (first part of your UNM email address), and the password is your UNM password.

Suppl. instructor: Paul Thorman (pthorman@unm.edu) will hold two additional recitation/problem solving sessions per week: Mondays and Thursdays 2-3PM in RH 114. Your input will help to determine what sections of the course to emphasize.
Prerequisites: Physics 161; pre- or corequisite: Math 264L
Physics 267: The 267 course will work on problem solving, for material related to the Physics 262 course. We will meet Wed 9:00-9:50AM in Regener 114.
