Reading Assignment for next year



Please read the following from Serway
and Jewett before class on January 3,
2005: Chapter 19, Sections 19.2-19.6
A Web-CT quiz is due on the Monday
morning of January 3 before class, which
tests your basic familiarity with Chapter 19
assigned reading.
This quiz is available today!
On Friday…





It is mandatory that you go to the room
assigned to your tutorial group.
The test should start at 9:00 sharp.
You should have no communication device
(phone, pager, etc.) within your reach or
field of vision during the test.
The test has eight equally weighted
multiple-choice questions (8 marks each).
The test has one multi-part problem
counting for 36 marks; show your work.
Don’t forget…




Your student card.
A non-programmable calculator without
text storage and communication capability.
A single original, handwritten 8 1/2 × 11
inch sheet of paper on which you have
written anything you wish. We will supply
any numerical constants you might need.
A dark-black, soft-lead 2B or 2HB pencil
with an eraser.
Some more words to the wise…




A good aid-sheet is well organized, easy to
read, and contains all the major equations
from the assigned sections from the reading.
Detailed specific problem solutions are very
unlikely to help. But feel free!!
Be ready to think; get a good night’s sleep on
Thursday.
Keep in mind: Your best 3 out of 4 tests will
count for 30% of your mark in the course.
Chapter 12: Simple Harmonic Motion



12.1-12.3: Mass on a spring, x, v, a,
energy
12.4: The Simple Pendulum
12.7: Resonance. Only basic ideas from
this section are important; not details of
the equations.
Chapter 13: Mechanical Waves




13.1-13.3: Description of waves, including
the traveling sinusoidal wave.
13.4, 13.5: Transverse waves on a string
13.7: Sound waves
13.8: The Doppler Effect

Chapter 14: Superposition of Waves:
Interference, Standing Waves, Beats




14.1: The Principle of Superposition
14.2: Interference
14.3-14.5: Standing Waves
14.6: Beats

Beats
Chapter 24: Electromagnetic Waves



24.3: We mostly skipped this section except
for the last 5 paragraphs: Light is a wave in
the E and B fields
24.7: The Electromagnetic Spectrum. You do
not need to memorize this or have it on your
aid sheet; we will provide you with frequency
ranges should they be needed.
24.9: Properties of Lasers. Only a basic
understanding of this section is needed;
ignore the gory details.
Chapter 25: Reflection and Refraction of
Light




25.1-25.3: Rays and the Law of Reflection
25.4: Snell’s Law of Refraction
25.7: Total Internal Reflection
25.8: Optical Fibres: only a basic
understanding of this section is needed;
ignore the gory details.

Chapter 26: Image Formation by Mirrors
and Lenses



26.1: Images Formed by Flat Mirrors
26.4: The Thin Lens Equation
26.5, 26.6: Lens Aberrations and Medical
Fibrescopes. Only a basic understanding
of these sections are needed; ignore the
gory details
