0101(49448)
Brill, D. TuTh...... 9:30am-10:45am PHY 1410
Required Textbook
The Physics of Sound, by Richard E. Berg and David G. Stork, 2nd Edition (Prentice Hall).
This course will cover Chapters 1 through 7, and parts of other chapters.
Some supplementary reading from the Internet will also be assigned.
An important part of the lectures are demonstration experiments.
Not all of these are described in the textbook, but any material discussed
in lecture or shown through demonstrations will be fair game for exams.
Class attendance is therefore strongly encouraged.
If you miss a class, it is your responsibility to find out what was
covered in lecture that day. The lecture topics and the demonstrations shown
can be found below on this web page.

The lecture and exam topics (but not exam dates) in the schedule below are tentative and subject to change. There is also room
for your input -- if you want more detail on some topic, or treatment
of a topic not listed, write an email to phys102@physics.umd.edu.
This schedule will be continually updated with experiments shown in lecture,
current homework problems and the solutions of past problem.
The links in the "Topics" column contain supplementary material, mainly applets relevant to the topic.

Students under CORE Program requirements must take both the lecture
(Phys 102) and the lab (Phys 103) courses during the same semester. In other
respects these are two independent courses, and receive independent grades.
Make sure separate grades are recorded for Physics 102 and for Physics 103.
Physics 103 starts the week of Sept 9. We of Phys 102 cannot give reliable
information about Phys 103, nor can we accept written work for Phys 103.*
The lecture part of this course (Phys 102) taken alone does NOT count as a non-lab science under CORE requirements.
Homework, Exams, Grading
There will be weekly homework assignments, due AT THE START OF CLASS
on the day they are due (generally Tuesdays) and two "hour" exams (actually lasting for our regular class time, 75 minutes).
For the homework you are allowed to collaborate with your classmates
(provided each of you contributes substantially), consult the TA, Professor,
or other textbooks. "Unauthorized assistance" in the sense of the honor pledge
would be copying solutions, say from a solution manual or from previous semesters'
solution sheets, without working through the problem yourself. Your course grade will be based on your homework, hour exams and final
exam, in the following way:
- Homework: 20%
- Hour Exams: 40% (25% for the better one, 15% for the other)
- Final: 40%
provided you made a good faith effort on ALL these components.
The TA does not have the authority to change grades or excuse you from
any scheduled class activity. Please come and see me for all questions
regarding grading.
STUDENTS WITH DISABILITIES
Students with a specific disability (permanent or temporary, physical or
learning) needing special accommodation during the semester should make
an appointment to meet with the instructor.
ACADEMIC INTEGRITY
Along with certain rights, students also have the responsibility to
behave honorably in an academic environment. Academic dishonesty,
including cheating, fabrication, facilitating academic dishonesty, and
plagiarism will not be tolerated. Any abridgement of academic integrity
standards will be referred directly to the Assistant Dean and forwarded
to the University's Office of Judicial Affairs. Confirmation of such
incidents can result in expulsion from the University. Students who are
uncertain as to what constitutes academic dishonesty should consult the
University publication entitled Academic Dishonesty.
Note the new requirement concerning a pledge on all examinations, and make
sure you can sign the pledge. For homework assignments you are asked to sign
a pledge covering all homework assignments on the first homework set.
1. Do the homework! The homework is designed to help you understand the material and
prepare for exams. Besides, the homework counts for 20% of your grade.
2. Ask questions! Either during lectures, after lectures, during office hours; or set up an
appointment.
3. Do the reading prior to lecture! You will get much more out of the lectures if you have
already begun to think about the material and formulate questions.
4. If you find yourself falling behind, ASK FOR HELP before it's too late, that is, before the second exam.
We regularly get requests during the last weeks of the term by
students who "need" a passing grade and want to redeem themselves by extra
work. Do not exprect such a chance of "redemption"!. In particular,
after homework solutions have been posted, you obviously cannot get
credit for handing those solutions in late. The best way to spend your
time is to prepare for the next exam. (This includes doing late homework
-- without looking at the solutions. As an encouragement we will record
that you handed in that homework, but we will not award the regular credit
that goes into your grade calculation.) You are advised to check regularly
the link to your grades (to be established), where all the grade
information we have currently about you can be found, so
any problem can be resolved in time. return to top
