PHYSICS 110C

ELECTROMAGNETIC WAVES

Spring Quarter 2008


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.  More Notes on Special Relativity.


SYLLABUS

Prof. Carl R. Gwinn
2015E Broida Hall
(805)-893-2814

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.
