Textbook:
Physics for Scientists and Engineers: A Strategic Approach with Modern Physics and MasteringPhysics (2nd Edition), by Randall D. Knight. There is a supplementary student workbook
that is included with the text if you buy it at the campus bookstore.
Topics and Outlook: In this course we will be introducing the basic ideas of electricity
and magnetism and light. This is a very large and very interesting subject, covering many
aspects of physics. In fact, by the time you finish this course, coupled with what you learned
in physics 8, you will have an introductory understanding of almost all of classical physics!
(The last major topic in classical physics, thermodynamics, will be covered during your next
semester, in Physics 10.) Electricity and magnetism covers far more than simply Coulomb’s
law. As we will see, with the three exceptions of gravity, the force responsible for radioactive
decay, and that holding the nucleus together, electromagnetism is responsible for everything
else in physics! In this course, we will begin with the simple laws of electrostatics, discussing
the electric field. We will introduce the concept of electric potential which, far from being a
simple mathematical convenience, represents a deeper understanding of the the origins of the
electric field. Next, we will discuss the basic circuit elements and learn how to analyze circuit
diagrams. From there we will discuss magnetism. As we investigate magnetic phenomena
we will see that while a static charge produces only an electric field, moving that charge
around creates a magnetic field ! A changing electric field produces a magnetic field, while
a changing magnetic field produces an electric field. It is clear, then, that electricity and
magnetism are not independent, but rather simply different aspects of the same thing - the
electromagnetic field ! Everything we have discussed can be condensed into four equations,
known as the Maxwell Equations, which we will then write down. Things are even more
interesting when we realize that light is wiggles and oscillations in the electromagnetic field.
Thus, in four very simple equations, Maxwell was able to unify electricity, magnetism, and
even light! It will be the topic of this course to tell this story in some detail.

Learning Objectives for Physics 9
Upon completion of Physics 9, you should understand :
• That electric fields are produced by electric charges.
• That magnetic fields are produced by electric currents.
• The concepts of capacitance, resistance, and inductance in conductors and ultimately
in electrical circuits.
• That electric and magnetic fields are not distinct phenomena, but are simply different
aspects of a single electromagnetic field.
• That light is oscillations in the electromagnetic field.
• That several waves can interact with each other leading to constructive or destructive
interference.
• That light bends and travels at a different speed when it passes from one medium to
another.
Learning Outcomes for Physics 9
Upon completion of Physics 9, you should be able to:
• Use Gauss’s Law to calculate the electric field from a static charge distribution.
• Use Ampere’s Law to calculate the magnetic field from a steady current distribution.
• Evaluate DC and AC circuits.
• Calculate induced electric fields from a changing magnetic field.
• Calculate induced magnetic fields from a changing electric field.
• Use the wave theory of light to calculate observable effects such as diffraction.
• Calculate the angle of refraction when light changes the medium of propagation.
• Calculate image properties using ray optics techniques.

Grading:
The grading will be based on the final (30%), one midterm (20%), 6 homework sets (40% total), and the discussion/lab sessions (10% total).
Homework
There will be 6 homework assignments, each assigned on Wednesdays, and due by
the beginning of class the following Wednesdays, giving you one week to finish them. We will
do our best to give plenty of partial credit, so always attempt the problems, even if you don’t
finish them. Because the homework solutions will be posted immediately, no late homework
will be accepted ! While you are of course permitted (and even encouraged ) to work together,
it is your responsibility to complete, understand, and hand in your own assignment.
Exams
Midterm: There will be one midterm, tentatively scheduled for Friday, July 9th.
The midterm will be cumulative, and will cover the material covered up to that point.
Final: Friday, August 6: 1:00 – 2:45. The final exam will be comprehensive.
Both exams are closed book. If some complicated formulas are needed (such as a nasty
integral) they will be provided, as will any required numerical values, etc. You may use
calculators. You should bring your student ID along so that your identity may be verified,
if necessary.
Discussion/Lab Sessions
Part of the course includes a discussion/laboratory (DL) session, led by Bron Davis, Luis
Martinez, and Jeremy Sanborn. These sessions meet four times a week and will contribute
a large amount to the course, so it is important that you attend these. During certain
sessions you will perform experiments, while during others you will work problems. These
DL meetings contribute 10% to your grade, and are manditory. The TAs are in charge of
the DLs!
• 001 (5192) PHYS 009 - 01C, 9:00 – 10:45 a.m. MW, CB 286 and TTh, SE 111.
• 002 (5193) PHYS 009 - 02C, 11:00 – 12:45 p.m. MW, CB 276 and TTh, SE 111.
• 003 (5194) PHYS 009 - 03C, 3:30 – 5:15 p.m. MW, CB 286 and TTh, SE 111.
There will be six labs each
meeting during your regularly scheduled DL time.
The labs will be held in
the Science and Engineering
(SE)Building 111.

Academic integrity
Academic integrity is the foundation of an academic community and without it none
of the educational or research goals of the university can be achieved. All members of the
university community are responsible for its academic integrity. Existing policies forbid
cheating on examinations, plagiarism and other forms of academic dishonesty. The current
policies for UC Merced are described in the UC Merced Interim Academic Honesty Policy
and Adjudication Procedures available from Students First Center, Student Life, Residence
Life and College One. Information is available through the Student Judicial Affairs link on
the Student Life web page. http://studentlife.ucmerced.edu/.
Examples of academic dishonesty include:
• Receiving or providing unauthorized assistance on examinations.
• Using unauthorized materials during an examination.
• Plagiarism - using materials from sources without citations.
• Altering an exam and submitting it for re-grading.
• Fabricating data or references.
• Using false excuses to obtain extensions of time or to skip coursework.
The ultimate success of a code of academic conduct depends largely on the degree to which
the students fulfill their responsibilities towards academic integrity. These responsibilities
include:
• Be honest at all times.
• Act fairly toward others. For example, do not disrupt or seek an unfair advantage over
others by cheating, or by talking or allowing eyes to wander during exams.
• Take group as well as individual responsibility for honorable behavior. Collectively, as
well as individually, make every effort to prevent and avoid academic misconduct, and
report acts of misconduct which you witness.
• Do not submit the same work in more than one class. Unless otherwise specified by the
instructor, all work submitted to fulfill course requirements must be work done by the
student specifically for that course. This means that work submitted for one course
cannot be used to satisfy requirements of another course unless the student obtains
permission from the instructor.
• Unless permitted by the instructor, do not work with others on graded coursework,
including in class and take-home tests, papers, or homework assignments. When an
instructor specifically informs students that they may collaborate on work required
for a course, the extent of the collaboration must not exceed the limits set by the
instructor.
• Know what plagiarism is and take steps to avoid it. When using the words or ideas of
another, even if paraphrased in your own words, you must cite your source. Students
who are confused about whether a particular act constitutes plagiarism should consult
the instructor who gave the assignment.
• Know the rules – ignorance is no defense. Those who violate campus rules regarding
academic misconduct are subject to disciplinary sanctions, including suspension and
dismissal.
