**Course Description:** The third
semester of a three semester sequence in introductory physics for physics,
math, chemistry, or engineering majors.
The subjects covered are oscillations and waves, both mechanical and
electromagnetic . These correspond **roughly**
to chapters 14-16 and 29-33 of the text*,*
though all chapters will __not__ be covered in depth. This is a calculus based sequence and makes
extensive use of MATH 140,141, 241, and some of 246. The course will stress a
quantitative understanding of physical phenomena and problem solving as well as
a clear qualitative understanding. It is not possible to cover all the course
material in lecture and students are responsible for the sections assigned in
the text. Lectures will concentrate on covering the major points and providing
insight into the material. To get the most out of lecture it is imperative that
students read the text before class.

**Exams:** There will be two
in-class exams during the semester and a **cumulative** final exam. The
schedule of the in-class exams is as follows:

Thursday March 4

Thursday April 15

The final exam will take place during the final exam period at the time and place specified in the Schedule of Classes.

Makeup exams will only be given for those with a valid __documented__
excuse (doctor's note, accident report, funeral notice, etc.). If you know ahead of time that you will miss
an exam you __must__ notify me before the exam. If you miss an exam due to an emergency let
me know as soon as you can, by any means possible. I will be very flexible for those with valid
excuses who have given timely notification.

**Homework**: Regular homework is assigned to try to insure that you
are keeping up with the course material and to act as a measure of your
understanding of the material. If you
are having difficulty with the homework this is a sure sign that you should
seek some assistance. Students are
encouraged to work together on homework but simply using another’s solutions
will not be helpful. We will be using WebAssign to assign and grade the
homework problems on the web. However, the WebAssign grading is just to aid
you; it will **not be included in your final grade**. Instructions will be
available soon. The following guidelines will apply:

Approximately 8 problems will be posted at
the website each Thursday and will be due at midnight the following Thursday.
You should work those problems to completion and submit the answers on the web.
You will be informed immediately if your answer is correct or incorrect and
will be allowed 4 retrys (**a total of 5
attempts**) to get the problem right. If you still do not get the correct
answer that is a sign you should seek help.

will be due in class the next Friday( eight days later )
or in my office by 5pm that day. This problem

will typically be
similar to the more difficult ones in the text.

**Quizzes:**
Each Friday there will be a quiz based on the homework assigned the week
before. No quiz on exam weeks. First quiz is Feb 6. Lowest quiz grade dropped.

**Discussion:** Discussion meets
once a week on Friday for the purpose of discussing homework problems,
reviewing important concepts from the lectures, and administering the quizzes.
On occasion, Friday class will be used for lecture but the quiz will remain on
Friday.

**Help:** Help in understanding the concepts and solving problems
can be obtained in a variety of ways. If
you have a question or any difficulty, try to take advantage of all the
available resources. These include:

1. discussions with me before or after class or
in my office - please do not be shy about seeing me;

2. your discussion section, which is designed for
just this activity;

3. meetings with the TA.

**Bulletin Board:** Please check every class day. I will communicate
important information there or post solutions.

**Grade:** Your grade will
be based on the following components:

Two in-class exams
45%

Final exam 35%

Quizzes 20%

All grades are subject to "curving" and there
is no set correspondence between numbers and letters. **In
general, a letter grade is only associated with the final course grade**, but
I can provide you an estimate of how I think you are doing, if requested. **Active
class participation** will improve your chances of obtaining the best letter
grade given your aggregate numerical total.
