1. Physics 262 Website: http://panda.unm.edu/Courses/Thomas/Phys262fa10/P262Syllabus.htm Exams: 7 midterms, scantron but not multiple choice Drop lowest. No make-up exams. Exams will be posted at least two weeks before being given. Numbers and geometric details will be changed. You will want to get an iClicker and MP. 0.1% of missed exam points (up to max 50%) per HW problem, iClicker quiz. http://panda.unm.edu/Courses/Thomas/Phys262fa10/P262Syllabus.htm

2. Written HW due approximately every week. 32.6, 32.8, 32.10 Due Mon Aug 30.

3. Electromagnetic “Discontinuities” Must Propagate at a speed

5. Our wavefront satisfies both “Gauss’s laws” because there is no enclosed charge or current, and fields on opposite sides of the box are the same.

6. There is a changing B flux as the wavefront moves by. This changing flux must be equal to the line integral of the E field. Only the back edge (gh) contributes to this line integral.

7. There is a changing E flux also. This gives another reqd relation between E and B.

8. Which could be EM waveforms? I II III A] I only B] I & II only C] all of them D] none of them

9. What direction are these EM waves moving? I II III A] +z B] -z C] along z, but cannot determine + or - D] Cannot tell at all
