1. COURSE GOALS AND OBJECTIVES
General
Goals:
The
introductory physics course sequence for engineers and scientists is intended:
a)
to help you to obtain a basic familiarity with the observations and
experimental results on natural phenomena which occur on the scale of
"ordinary sized" objects traveling at "ordinary speeds"
(CLASSICAL PHYSICS);
b)
to develop a working knowledge of the small number of fundamental theories
which explain the diverse phenomena which occur in nature by applying them to
derive the formulas which apply to particular situations using rigorous problem
solving methods.
In
particular in 95.144 Physics II you will develop an understanding of the
phenomena of classical optics, classical electromagnetism as well as the
theories used to explain them.
Specific
Learning Objectives:
The following are some examples of the specific
learning objectives on which you will be tested in the homework assignments,
quizzes, three one hour examinations and the final examination (The Learning
Objectives are listed at the beginning of each section of the lecture notes.):
a) To be
able to demonstrate your understanding of the experiments and concepts
underlying optics and electromagnetic theory by correctly answering multiple
choice questions in the examinations on these topics which are presented in the
textbook and lectures.
b) To be
able to calculate the interference and diffraction maximum and minimum points
on a screen due to the passage of electromagnetic waves through a single slit,
pair of slits or a grating,
c) To be able
to calculate the total force on a test charge and the electric field due to a
set of charges (point or continuous) using the superposition principle for
forces and fields,
d) To be
able to calculate the total electric potential due to a set of charges (point
or continuous) using the superposition principle for electric potentials,
e) To be

for the resulting electric or magnetic fields,
f) To be
able to calculate the electromagnetic force (Lorentz force) on a test charge
(stationary or moving at a constant speed) due to applied electric or magnetic
fields,
g) To be
able to calculate the acceleration, velocity and position of a test charge as a
function of time due to a constant electromagnetic force,
h) To be
able to apply the Faraday or Ampere-extended laws to time varying magnetic or
electric fluxes and derive the formulas
for the resulting induced electric or magnetic fields and forces,

95.141. Co-requisites: 92.132, 96.144.
3. PREREQUISITES AND
CO-REQUISITES
All
students should have successfully completed the 95.141 PHYSICS I course at
UMass Lowell or its equivalent at another institution. All students must either be currently
enrolled in 92.132 CALCULUS II or have successfully completed it at UMass
Lowell or its equivalent at another institution. In addition, all students must either be currently enrolled in
the co-requisite laboratory course 96.144 EXPERIMENTAL PHYSICS II or have
successfully completed it at UMass Lowell.
All equivalency determinations must be made by the department giving the
corresponding course at UMass Lowell if you were not already given transfer
credit upon admission to the University.
Please contact the transfer credit evaluator in the appropriate
department.
4. COURSE FORMAT: LECTURE, RECITATION AND LABORATORY
LECTURE:
Our
course meets five times per week, two lecture classes, two recitations and one
laboratory. The lecture schedule is
listed in item 12. You should have read the
lecture material to be covered in the textbook and Coursepack before attending
each lecture. You may be asked questions on this material during the lecture
which you will answer using the PRS transponder. The lectures are primarily intended to
familiarize you with the phenomena being studied and the basic physical
concepts used to understand the phenomena.
The lectures will be interactive using the electronic transponder (PRS)
and highlight the important points in the text, clarify confusing concepts,
illustrate some phenomena with demonstrations and in some cases supplement the
textbook material with new topics.
Therefore, you should attend all lectures, and take supplementary class
notes particularly when a topic is presented which was not clear from your reading.
Class attendance and participation will be counted toward your course grade.
(See section 9, How Your Grade Is Determined).
Your notes should be kept in an organized manner in a notebook(There are
Class Notes pages in the Coursepack.) for reference when studying for
examinations.
RECITATION:
Recitation classes are smaller than the lecture class and are intended to help you to review the homework assignments with particular emphasis on problem solving techniques, to answer your questions on the lecture material or the assignment, to highlight your strong and weak areas by giving you a quiz and to prepare you for the examinations. The recitation schedule is listed in item 12. You should do the homework assignments regularly prior to class. The assignments will be graded and returned to you as soon as possible after you submit them. You should also write down the problem solutions given by your recitation instructor in your notebook for future reference if you had difficulty with any of the problems in the assignment.
Your recitation instructor may give you extra
credit assignments to improve your homework grade if he/she feels that it is
appropriate. You will also have practice assignments and tests available on the
computer PhGradeAssist2
system which are not graded but will give you immediate feedback on your
understanding of the homework assignments and preparation for the tests.
LABORATORY:
The
laboratory class is limited in size so that each student will have an
opportunity to get hands-on experience with operating the apparatus, observing
the phenomena and making precise measurements from which the results are
extracted by data analysis techniques.
Furthermore, a written report for each experiment is required in order
to help you develop the technical writing skills necessary in all areas of
engineering and science. Every effort
is made to coordinate the experiment to be performed with the lecture material.
However, this may not be possible in all cases. A few topics such as geometrical
optics may be covered only in the laboratory. Therefore, you should take
careful notes during the pre-laboratory lectures.
5. EXAMINATIONS AND EXAMINATION SCHEDULE
Common
examinations (EXAM I, II, III) will be held during the lecture hour on the
dates listed below. The room
for all three of the examinations will be the lecture room. In addition, there will be a comprehensive
three hour FINAL EXAMINATION during finals week at the end of the
semester. The time and place for the
FINAL EXAMINATION will be announced near the end of the semester. You are required to attend each examination
at the officially announced time. See
ATTENDANCE/ABSENCE AND DISABILITIES POLICIES in item 8 below.
You must
bring pencils, erasers and a calculator to each examination session. A formula sheet will be provided with each
examination listing all formulas for the entire course. YOU WILL BE ASKED TO TURN OFF ALL CELL PHONES AND PLACE THEM IN FRONT
OF THE ROOM. The examinations will be graded and returned to you in your
recitation class within one week. Upon
receiving your examination you should check the grading against the solutions
which will be reviewed in recitation class by your instructor. The average
grades will be posted on the Forum page of the course website. If you have any questions about the score or
grading policy, you must write the problem number you want re-graded and the
reason on the front cover of the examination only and turn the
examination in to your recitation instructor at the next class. As a result
of the regrade you may get additional points, no change in your grade or your
grade may be decreased. This
procedure will not apply to the FINAL EXAMINATION. However, you may request to see your FINAL EXAMINATION within the first
two weeks of the next semester by contacting your recitation instructor who is
responsible for your course grade and can make changes if necessary.

6. HOMEWORK POLICY
Homeworks
are assigned to you twice each week and are due on the dates indicated in the
LECTURE/RECITATION ASSIGNMENT SCHEDULE in item 12 below. All of your homework will be graded and
returned to you as soon as possible. The two lowest homework grades will be
dropped from consideration. If
you do not complete your homework on time, it will result in a grade of
"0" unless you have an absence approved by your recitation instructor. At the discretion of your recitation
instructor you may be assigned extra credit homework on paper or PhGradeAssist2
which will count toward your recitation grade or practice assignments and tests
on the computer GradeAssist2 system which will not be counted toward your
recitation grade.
One of the best ways to do your homework is to form a homework study group with your friends and work on problems together. Each of you, however, must submit your own individual solution for each problem set to your recitation instructor by the due date. Working as a team will help you to improve your understanding as well as your grade.
To use the PhGradeAssist2
system for practice homework and/or homework extra credit work you must have
access to a computer connected to the internet either at your residence or on
campus at UML North or UML South Tutoring Centers. First, go to the course
website, go to the Materials page and click on PhGradeAssist2.
Select Student Login and create a profile with your personal User ID purchased
with your course materials and a password. Enter your ID and password. Select
the assignment your want to work on by clicking on it. Follow the directions
given on the website to complete, submit and have the assignment corrected with
feedback on errors.
You
should follow the homework format below for the paper homework assignments
(instead of PhGradeAssist2
exercises) to make it easier to grade your work accurately and to develop your
problem solving ability.
1. Do
your homework on 8 1/2 x 11 in. sheets of paper.
2. Your name (last name first) should be printed in
the upper left hand corner of each page along with the date, assignment no.,
course no. and section no.
3. You
should place the problems in the numerical order assigned.
4. Include a suitable diagram, correctly labeled
with the given information as well as the quantities to be determined for each
problem.
5. You should first write equations representing
the fundamental principles of physics which apply to each problem in terms of symbols before attempting a
solution.
6. All the mathematical steps necessary for the
derivation of a formula for the problem should be written in terms of symbols,
algebraically simplified, checked for the consistency of units, and then the
given numbers substituted to obtain a numerical solution with the correct
units.
7. The solutions for the odd numbered problems can
be found in the solution manual, but you should first try to solve them
yourself.
8. If you are asked to make a graph, it should be
done using either a computer plot package or by hand neatly on graph paper.
9. You must staple all the pages of a single
assignment together in order in the upper left hand corner before turning in
the assignment. (If two assignments are collected on the same date, they should be kept
separate.)
7.
QUIZ POLICY
Your
recitation instructor will typically give at least one ten to fifteen minute
quiz per week. This quiz may be announced
or unannounced and will cover recent material similar to the homework
problems. You must come to class
prepared with a pencil, eraser and calculator.
Your two lowest quiz grades will be counted as dropped by your
recitation instructor. Unexcused
absences will result in a quiz grade of "0" for that particular quiz.
No make-up quiz will be given.
8. ATTENDANCE/ABSENCE AND DISABILITIES POLICIES
ATTENDANCE/ABSENCE
Your attendance is required at all lecture, recitation and
laboratory classes. Attendance will be
taken in lectures using your responses for the PRS system and in recitation
classes, quizzes will serve as proof of attendance. Poor attendance in either lecture or recitation classes will lead
to a drop in your grade.
There
are no make-up examinations for EXAM I, II or III. Illness on the day of an examination must be verified by
submission of a letter from a physician or nurse to your recitation instructor
showing that you were seen prior to or on the day of the examination and attest
that your illness made you unable to take the examination. Notification of all other absences, i.e.
varsity sports, family events, etc. must be made one week in advance by written
request and approved by your recitation instructor.
Only
one approved EXAM I,II or III absence is allowed. In that case your course grade will require increased emphasis on
the FINAL EXAMINATION (See item 9). If
you are unable to take the FINAL EXAMINATION for a reason acceptable to your
recitation instructor, you may request in writing an incomplete grade for the
course within 48 hours of the FINAL EXAMINATION (See the Undergraduate Catalog
for the procedure). Your instructor
will calculate your grade as if your FINAL EXAMINATION grade was "0"
and submit both the incomplete grade "I" as well as the calculated
grade which will become your permanent grade for this course if a make-up FINAL
EXAMINATION is not taken by the deadline for incompletes. (See the University
Calendar).
DISABILITIES
If you
have either a learning disability or a severe physical handicap, you may be
eligible for extra time during the EXAMS and the FINAL. Discuss your situation with the
9. HOW YOUR GRADE IS DETERMINED FOR LECTURE/RECITATION
Your grade
is based on the total number of points you earn during the course. The maximum number of points you can earn is
700 which is broken down as follows:
30 pts. Lecture Attendance & Participation
170
pts. Homework(85) & Rec.
Quizzes(85)
100
pts. EXAM I
100
pts. EXAM II
100
pts. EXAM III
200
pts. FINAL EXAM
---------
700
pts. TOTAL
Remember,
in evaluating your homework and quiz scores the two lowest homework and quiz
grades are dropped. If you
are excused from EXAM I, II or III, the FINAL EXAMINATION will count 300 pts. If you have six or more unexcused, recorded
absences in either recitation or lectures, your course grade may be reduced by
one step in the letter grade scale.
At the end of the semester after all grades including the FINAL EXAMINATION are added together your lecture instructor in consultation with all the recitation instructors will determine the points required for the various letter grades. As a rough estimate of your performance as you progress through the course the following conversions between your percentage score at a given point in the course and your letter grade are listed below:
ROUGH ESTIMATES OF
GRADE CONVERSIONS*
A 80% - 100%
A- 77% - 79%
B+ 75% - 76%
B 65% - 74%
B- 62% - 64%
C+ 60% - 61%
C 50% - 59%
C- 47% - 49%
D+ 45% - 46%
D 35% - 44%
F 0% - 34%
* (The final conversions determined at the end of
the course may differ slightly from those listed above.)
Make sure
you do not sacrifice points needlessly by missing lectures, homeworks and
quizzes.
You will
be given a separate grade for the laboratory course 96.144. How this grade is determined will be
explained by your laboratory instructor.
10.
HELP IF YOU HAVE A PROBLEM
If you
have a problem, your recitation instructor is the first person you should
contact either during his/her office hours which are posted on his/her office
door or by appointment at a mutually convenient time. For major unresolved problems see me, Prof. Karakashian, in Olney
