**Catalog course description:**

A continuation of Physics 10. Physics 11 is divided between classical and modern topics, including electricity and magnetism, circuits, special relativity, quantum aspects of nature, atomic and nuclear structure, and elementary particles.

**Course Themes and Emphases: **

• the microscopic structure of matter

• fundamental forces and new forms of energy

• extension of human "experience" to small spatial scales (quantum physics) and high velocities (relativity)

**Text:*** *

**Physics, Principles with Applications**, 5th Edition, by Douglas C.
Giancoli, Prentice Hall (Upper Saddle River, New Jersey, 1998).

**Grades:**

Final grades will be based on the following weighted components:

1) Final Exam 25 %

2) Hour Exams (2 X 12.5%) = 25 %

3) Laboratory 25 %

4) Homework 10 %

5)
Quizzes 15 %

**Exams:**

There
will be two midterm exams and one final, comprehensive exam. Each exam will be
closed book. Required formulae will be
provided on the exam, but you will need to be able to recognize the meaning of
the symbols in each formula and how to use them to solve problems such as those
encountered in homework and lecture examples.
Exam problems will be a mixture of quantitative problems like those
encountered in homework sets and conceptual problems (multiple choice and short
answer) like those encountered on weekly quizzes

**Laboratory: **

A list of laboratory topics for each week is given below. Mr. Fontana will provide details on the operation of the laboratory portion of the course, including grading policies for labs.

Week 1: Electric Field Mapping

Week 2: Electric Circuits I (DC Circuits)

Week 3: Charged Particle Motion in a Magnetic Field (e/m)

Week 4: Electric Circuits II (AC Circuits)

Week 5: Measurement of the Speed of Light (c)

Week 6: Special Relativity Simulation

Week 7: The Photoelectric Effect (h/e)

Week 8: The Bohr Model and the Hydrogen Spectrum

Week 9: Nuclear Physics I

Week 10: Nuclear
Physics II

**Homework:**

Every
Wednesday, homework sets will be collected for grading. No late submissions will be accepted. Homework assignments will focus on
quantitative problems. You are strongly
urged to work additional problems on your own, beyond those that are required.

**Quizzes:**

Every
Friday (except on Midterm exam days, winter break and the last class of the
term) there will be a short (10 minute) quiz.
Weekly quizzes will focus on conceptual problems, will generally be
multiple choice, short answer and/or true-false questions that test your
understanding of the concepts covered in the lectures and reading assignments
for that week.

**Help Sessions:**

Help sessions will be every Tues. and Thurs. evening (beginning on Thursday, January 6) 8-10pm in Youngchild 90. A student assistant will run most of these sessions.
