Announcements:
Final Exam: Has been graded and course grades posted via
eGrades. You can pick up your exam
in 2015E Broida. Office hours are
irregular this summer but if you would like to look over your exam, you can
contact me via email
and arrange for pickup; or drop by. Have a great summer!
Some References
on 4-Vectors: Gravitation (by Misner, Thorne and Wheeler: Chapters
2 and 3). Classical Theory of
Fields (by Landau and
Lifshitz: Chapter 1). These are on
reserve in the library.
Notes on Special Relativity: Are in the “Notes”
folder in the phys110C webpage area.

Office Hours: W 2:00 pm - 3:00 pm, F 1:00 pm - 2:00 pm
Lectures: 11:00 am – 11:50 am, MWF, Arts 1251
Discussion Section: 5
pm - 6 pm, Tues, Physics Study Room in Broida
TAs for Homework and Discussion:
Michael Johnson
Office hours: 8-9:30
am and 4-5 pm Thurs, 4:20-6 pm Friday, in the Physics Study Room
Required Textbook: David J.
Griffiths, Introduction
to Electrodynamics, 3rd edition. Wangsness, Marion & Heald, and
Lorrain, Corson & Lorrain are on reserve in the Reserve Book Room of the
Library, as is Electrodynamics by Jackson, the traditional graduate text.
COVERAGE: Electromagnetic waves, gauge
transformations and special relativity, radiation from charge and current
distributions, and (if time permits) introduction to physical optics.
Objectives: The goal of this course is to learn to
solve physics problems, to come up with new ways to solve problems, and even to
come up with new problems. This involves learning the theoretical
framework of physics, learning techniques, and practice. This quarter is
dedicated to these activities for electromagnetic waves.
Tests and Grading: We will have 2 midterms, each of which will count for 11% of the
grade. Homework will count for 33%. The final will count for 45%. I will curve
the exams and homework. Typically for upper-division physics classes I’ve
taught in the past, a grade of 92% or higher yielded an A, and 50% has been the
dividing line between C and C-. See the policy on missing
homework or an exam.
HOMEWORK: Homework
will be assigned each week, to be turned in by 6pm on Friday in the box marked "Physics
110C" just outside the Physics Study Center. Graded homework will be
returned in discussion section the following week. Homework solutions will be
posted on the UCSB library's eres
page. See Prof. Gwinn or the TAs for the password.
