      and by appointment.

Lecture Hall/Times: The lectures for this class will take place in NECKERS 440 from 1:20-2:20 M-F.

Once the lecture has started, please do not gossip, distract your colleagues, or otherwise disturb the class.


Southern Illinois University Carbondale is committed to providing a safe and healthy environment for study and work. Because some health and safety circumstances are beyond our control, we ask that you become familiar with the SIUC Emergency Response Plan and Building Emergency Response Team (BERT) program. Emergency response information is available on posters in buildings on campus, available on BERT's website at, Department of Safety's website (disaster drop down) and in Emergency Response Guideline pamphlet. Know how to respond to each type of emergency.

Instructors will provide guidance and direction to students in the classroom in the event of an emergency affecting your location. It is important that you follow these instructions and stay with your instructor during an evacuation or sheltering emergency. The Building Emergency Response Team will provide assistance to your instructor in evacuating the building or sheltering within the facility.


TEXTBOOK: Physics for Scientists and Engineers (7th Edition) by Raymond A. Serway and John W. Jewett {Brooks/Cole--Thompson} 

CLICKERS: Clickers are available at 710 Book Store and the University Bookstore in the Student Center.  In addition, you may want to look at some of the instructions HERE.

HOMEWORK: There will be homework assignments given during the semester, aprroximately one assignment per week. Not all homework problems will be graded.   However, you must hand-in all of your homework solutions. The solutions for each homework assignment will be posted on the class web site on the day listed on the web page of this course.

The homework assignments will be posted at the aforementioned URL site.  It is your responsibility to check the web site to keep track of the assignments.  In order to do this, you should visit the course site at least once a week, if not more often.

 In order to really grasp the concepts, you will need to do the homework assignments yourself and to check your skills by comparing your solutions with the ones posted on the web.

Student Conduct Code


  • Below are the prerequisites for this course: 
    1. You must have completed Math 150 (Calculus I) with a  grade of "C" or better.
    2. You must have completed Math 250 (Calculus II) with a grade of "C" or better.
    3. You must have completed Physics 205A with a grade of "C" or better. 

    Tentatively, the following topics will be covered during the semester:

    Electricity and Magnetism:
        Electric Charges, Forces, and Fields (Chapter 23)  

        Electric Flux and Gauss's Law(Chapter 24)  
        Electric Potential and Potential Energy (Chapter 25)  
        Capacitance and Dielectrics (Chapter 26)  
        Current and Resistance (Chapter 27)  
        Direct Current Circuits (Chapter 28)      
        Magnetic Forces and Fields (Chapter 29) 
        Sources of Magnetic Fields(Chapter 30) 
        Faraday's Law (Chapter 31) 
        Inductance (Chapter 32) 
        Alternating Currents (Chapter 33) 
        Electromagnetic Waves (Chapter 34) 
    Light and Optics (as time permits)
        Properties of Light and Geometric Optics (Chapter 35) 

        Image Formation (Chapter 36) 
        Interference of Light(Chapter 37) 
        Diffraction and Polarization (Chapter 38) 


    Since the main objective of this course is to understand and then successfully apply the fundamental concepts of physics to solving problems, it is important to have good math skills. To do well in the course, you need to have good math skills in algebra, trigonometry, and calculus (both differential and integral calculus). I strongly urge you to freshen up your math skills for this course. Please visit the Math Department's web site (see below) to review the relevant material in trig, algebra, and calculus, in particular review the materials posted for math 107, 108, 109, 150, and 250.

    Please remember, in the end, you will earn your grade by your hard work and your performance.


    CLASS WORK: There will be several Homework assignments during the semester. You will be asked to turn these in for a grade. These grades, along with your class participation, will count as your class work grade which will comprise 6 % of your final grade for the course.  

    EXAMS: There will be 3 exams/tests during the semester. The date of the exam will be announced by being posted on the class web site two or three lectures before the exam.  Therefore, it is important that you check the class web site often (at least once per week). 

    The exams will be closed textbook.  However, a formula sheet listing the equations from the chapters over which the exam is based will be posted on the class web site.  It is your responsibility to download the equations, print them, and bring them with you on the exam and the Final Exam days. You are NOT allowed to consult class notes, books, and programmed solutions on your calculators.

    On the day of the exam (or final exam) you can bring copies of Appendixes A and D, however, this does not imply that you will be allowed to consult the textbook during the exam and Final Exam.

    On the day of the exam, bring your student ID.  It will be checked.

    You may use calculators during the exams or final exam, so bring one of your own.  Any information brought into the exams through programmable calculators constitutes academic dishonesty and will be subjected to judicial proceedings according to university rules (see Rule section).

    The exams will be based on any information discussed in the lectures and/or in the textbook.  Predominant content will be from the lectures (this does not mean the exam questions will be identical to the numerical problems we solved in class).  Consequently, it is important for you to attend lectures. 

    The lowest exam grade will be dropped. This constitutes reasonable accommodation for university sanctioned activities scheduled on days when exams are to be taken. It is very important that you do not skip exams just because you want to do so.  If you miss an exam, it will be counted as your dropped exam. Therefore, it is imperative that you take all the exams because that will provide you flexibility and will help you maintain a good grade.


    The exams collectively count 54 % toward the final grade in the course.


    The final exam counts 40 % toward the final grade in the course. The final exam will be a comprehensive exam.

          Final Exam:

     Date: August 6, 2010 (Friday)
     Time: 10:00 a.m. to 11:50 a.m.
     Place: Neckers 240


    In case the fire alarm or the alarm is pulled during the exam or the Final Exam, this is what we will do:

    In case the fire alarm or the alarm is pulled during an exam and since we will have to vacate the lecture hall, the exam in question will not be graded. Instead, a replacement exam will be given on Friday at  8 P.M. The exact date will be posted on the web site.

    In case the fire alarm or the alarm is pulled during the Final Exam, then a replacement final will be administered on the Friday night of the final exam week at a place and time to be listed on the class’ web site.


    The following weighting will be used for exams and final exam in computing the final grade:

    Exams    =     54.0 %
    Class       =      6.0 %
    Final       =    40.0 %
    Total      =     100 %

    KEEPING UP WITH GRADES: Grades will be posted.  You should visit office hours at least once after the first exam to find out how you are doing in the class.  It is suggested that you do so more often.  It is your responsibility to avoid surprises and know how you are doing at any given time throughout the course.  

    There is a help desk outside of Neckers 240 where you can ask questions. Click HERE for available times.
