PHY 224 Electricity and Light

Syllabus and General Information for Winter 2003

Prerequisites:

PHY 223 and MTH 121.

Brief Description: 

PHY 224 is a continuation of PHY 223 that covers static and current electricity, magnetism, and light.  It counts for 5 semester credit hours and instruction consists of five 50 minute class meetings per week and one 110 minute lab per week.  You will need to obtain the course materials listed below and you will be responsible for (that means you will be tested on) the material covered in the lectures, recitation sections, laboratories, and homework.

Required Course Materials:        

·        Physics for Scientists and Engineers, 5th Ed., by Serway and Beichner.

·        Lab manual

·        graph paper

·        Calculator with algebraic operations plus trigonometric, exponential, and logarithm functions

·        12" clear plastic ruler

Course Objectives:

After successfully completing this course, I expect you to be able to:

1)       Work effectively with your colleagues

2)       Construct operational definitions

3)       Apply the concepts of charge conservation and quantization to determine charges on objects

4)       Determine the forces and torques acting on charged objects using Coulomb’s Law

5)       Determine electric fields produced by charge distributions using Coulomb’s Law

6)       Determine electric and magnetic fluxes through specified surfaces

7)       Determine electric fields produced by charge distributions using Gauss’ Law

8)       Determine electric potentials produced by charge distributions

9)       Determine the potential differences across, and electric currents flowing through, resistors, capacitors, and inductors in direct current and alternating current circuits

10)   Determine the effective resistance, capacitance, and inductance of series and parallel combinations of resistors, capacitors, and inductors

11)   Determine the magnetic force acting on moving charges

12)   Determine the magnetic field produced by electric current or displacement current

13)   Determine the induced electromotive force using Faraday’s Law

14)   Determine the energy stored in electric and magnetic fields

15)   Apply Maxwell’s equations to calculate electric and magnetic fields and their effects

16)   Determine the paths of light rays propagating through different materials and interfaces, and calculate the location of images formed by optical systems, using the laws of geometric optics

17)   Predict quantitatively the irradiance patterns produced by interfering electromagnetic waves

18)   Predict quantitatively the irradiance patterns produced by diffracted electromagnetic waves

19)   Write effective technical (lab) reports

Meeting Times: 

PHY 224 is scheduled to meet every weekday from 9:00 - 9:50 AM.  We will meet in 307 Strong Hall on MWF beginning Monday, January 6, 2003 and in 341 Strong Hall TTh beginning Tuesday, January 7, 2003 until the last class on Thursday, April 17, 2003. Class does not meet on the following days: Monday, January 20, 2003 because of Martin Luther King, Jr. Day; Monday, March 1, 2003 through Friday, March 5, 2003 because of Winter Recess; and Friday, April 18, 2003 because of Spring Recess.

Attendance and Participation

I strongly encourage you to attend and to actively participate in class (both lecture and recitation)!  Active participation is important because just passively listening has been shown to be a significantly less effective way to learn physics.   Besides, it's much more fun if we hear from everybody!   I'll keep attendance but won't count it towards your grade.  Although I will not figure participation into your grade, let me just say that you stand to gain by participating since you get to ask questions that you want answered, and you get help that you otherwise wouldn't. 

Laboratory:  (15% of your course grade)

There is a laboratory that must be taken with this class.  The labs begin the week of January 6, 2003 and meet for 110 minutes each in 320 Strong Hall.  You will need graph paper, a 12" clear plastic ruler, a scientific calculator, and you will need to purchase the lab manual.  The laboratory will count for 15% of your course grade.  During lab meeting times, you will take data; later, outside of lab, you will write a report on the data that will be due the following week.

Homework:  (15% of your course grade)

Homework assignments will consist of assigned reading, questions, and problems.  You will submit your homework solutions and answers in writing or by the internet, as specified in the assignment.  Homework will be assigned weekly and will count for 15% of your course grade. Illegible homework will not be accepted. If you have difficulty writing clearly, you should arrange to have someone type or clearly write your homework for you.  Late homework will not be accepted unless you have a documented excuse from a health care provider or clergy member. Note:  academic dishonesty of any kind (e.g., plagiarism) will be penalized; see the Student Judicial Services web page at http://www.dsa.emich.edu/sjs/index.html.

Homework Quizzes:  (18% of your course grade)

A homework quiz will nearly always be given immediately after the homework assignment is collected.  The quizzes will count for 18% of your course grade and are designed to provide you with feedback regarding how well you understand the concepts and principles covered in the homework assignment.  This gives you a chance to recognize whether any topics give you difficulty before the exams so that you have a chance to resolve the difficulty and succeed on the exams.  The homework quizzes will cover material discussed in the lecture, the text, and the homework assignments.

Exams:  (52% of your course grade: Preliminary Exams, 40%; Final Exam, 12%)

There will be 6 preliminary exams during the semester and one final exam at the end of the semester.  The preliminary exams will take place on alternate Fridays, beginning January 17, 2003.  Your 5 best preliminary exam scores will make up 40% of your course grade and the final exam will make up 12% of your course grade.  There are no make-up exams.  The final exam is not cumulative and is scheduled to take place from 9:00 AM to 10:30 AM on Wednesday, April 23, 2003, in 307 Strong Hall.

Grading: 

Your course grade will be calculated from your laboratory work, homework, homework quiz scores, five best preliminary exam scores, and the final exam.  The weight of each of these is as follows:  laboratory work 15%; homework 15%, homework quizzes 18%, preliminary exams 40%, final exam, 12%.  There is no curve for this class:  you are competing only against yourself, not your fellow students.  For example: say that you scored 100% of the laboratory points, 85% of the homework, 90% of the homework quizzes, 80% of the preliminary exams, and 90% of the final.  On a 100 point scale, that gives (1 x 15 = 15) + (.85 x 15 = 12.75) + (.9 x 18 = 16.2)  + (.8 x  40 = 32) + (.9 x 12 = 10.8) = 86.75, which is a high B.  The grades will be determined as follows*:

*If you earn less than 60% of the total possible lab points, you will earn a grade of E for the course.
