ChemPhys 173 - Semester Review

First Semester, 2007-2008


Background Information

The physics exam for ChemPhys 173 will be held on Monday, January 14, 2007 during your regularly-scheduled physics class. (If there is a snow day or some other unforeseen reason for the cancellation of school, then check this page for an update on time and location.) The exam will be a 50-minute exam covering all topics learned during the first semester. The exam will be started the moment the period begins and will be collected at the end of the period; extra time will not be alloted. If there are special circumstances that require that you need additional time, then see Mr. Henderson privately before the day of the exam to discuss those circumstances; unless such arrangements are made prior to exam day, no extra time will be allotted.

Most questions are multiple-choice; there are a few problem-solving questions. Many of the multiple choice questions include up to 10 possible choices - from a through e and such choices as ab, ac, ad, etc. Planning to guess on questions is unlikely to be a wise alternative to planning to prepare. The MC answers will be placed on ScanTron forms; the solutions to the problems will of course be worked out on a separate sheet of paper. Each class period/Mods will have a separate form of the exam with nearly identical or at least very similar questions. The exam is not likely to be curved; it would not be surprising if there are several perfect scores. Your exam score in physics will be averaged with your exam score in chemistry. This averaged score will comprise 20% of your semester grade in ChemPhys.


Contents of Exam

There are approximately 55 multiple choice questions and approximately 7 problems on the final exam. The questions cover the following topics:


Approx. # of Qs

The Law of Reflection, Diffuse Reflection, Plane Mirrors

~7 Qs

Curved Mirrors, Ray Diagrams, Object-Image Relations, Mirror Equation

~11 Qs

Refraction, Snell's Law, Total Internal Reflection, Critical Angle

~10 Qs

Lenses, Ray Diagrams, Object-Image Relations, Lens Equation

~10 Qs

Wave Basics - teminology, wave equation, types of waves

~10 Qs

Sound Waves - Nature, Characteristics, Behaviors, Resonance and Harmonics

~12 Qs

Very few of the questions require the use of a calculator. Most questions can be answered quickly. Few questions involve in-depth analysis. Most calculations are straight-forward; there will be very few blue-coded problems. Keep in mind that all questions are worth the same number of points. Do not blow 5-10 minutes trying to solve a Refraction/Trigonometry question. If such a question is that difficult for you, then count it as a loss and continue on with those questions which you do know; return to the troublesome questions at the end of the test.

The following math equations will be provided on the test:

v = f•lambda
v = d/t
f = 1/T
1/do + 1/di = 1/f
M = hi/ho = - di/do
v = c/n
ni • sin(thetai) = nr • sin (thetar)
dB = 10• log(I/1 x 10-12 W/m2)
I = P / ( 4•PI•R2 )

How to Prepare

There are numerous ways to prepare for the test. The best ways are those which help you learn the material. This will be different for differnt learners with different learning styles. The main thing is to devote some time to the preparation process. There are numerous preparation tasks which can be done which should help. The following provides such ideas:
