**Course:** Physics 121 is the second of a two semester course. We
begin with an introduction to electricity and magnetism. We then
combine these subjects to consider various aspects of electromagnetic
radiation, such as optics and the doppler effect. Finally we
investigate topics of modern physics, including Einstein's theory of
relativity, quantum mechanics and nuclear reactions.

**Text: ** Walker, J.S. *Physics, 4th Edition* required.

**Course Website:**
http://www.physics.sfsu.edu/~chris/physics121/
provides lecture notes, syllabi and exam reviews.

**Homework:** The best way to learn physics is by solving problems
on your own and in small groups. Students who do not invest their own
time and effort on homework problems have done poorly on exams.
Feel free to discuss the homework
with other students and with the instructor, but in the end you must
work the problems yourself. Homework problems make up 15% of your
grade. Assignments will be given every week or two, with a
total of 10 for the semester. Late homework is not accepted, but
students' lowest homework score will not be counted toward their
grade.

Homework is submitted online at the www.WebAssign.net. site. All
students must register at this site (cost ~ $40/course)
during the first week of class, and begin to submit assignments.
Please register (using the name by which you are known
in university records)

**Exams:** There will be two midterm exams and a final exam. Exams
are closed book and closed notes. At each exam, students should bring
a calculator, and one 8.5 x 11" piece of paper per exam containing
formulas and notes written by the student. Formula sheets from
previous exams in this class may be brought to later exams, for a
total of three such sheets at the final exam.

** GRADES**
Course will be graded on a curve. Course grades will be determined
according to these weightings:

- Homework: 15%
- Midterm exams: 25% Each
- Final exam: 35%

**Learning objectives:** Students successfully completing
this course will, among other things, be able to:

- Compute the net force on a charge, considering all components
- Describe the effects of electric and magnetic force fields.
- Define the electrric potential (voltage)
- Use Newton's Second Law to predict the motion of charged particles
- Use understanding of gravity (from Phys. 111) as an analogy for electromagnetism.
- Apply the conservation of energy to electrical systems
- Analyze circuits
- Be able to describe light as an electromagnetic wave and explain how EM waves propagate.
- Analyze optical systems quantitatively, and using ray-tracing
- Know the principles of Relativity, and their consequences
- Utilize the equivalence of mass and energy in calculations
- Provide evidence from experiments that refute classical physics and support quantum physics
- Understand the implications of wave nature of matter
- Predict the products of a nuclear reaction, and calculate the energy released.
