Reading Assignment for next year Please read the following from Serway and Jewett before class on January 3, 2005: Chapter 19, Sections 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 : 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 : 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 : Standing Waves 14.6: Beats

Standing Waves

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 : 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.

Total Internal Reflection

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
