  1. PHY138 – Last Waves LectureQuarter Review, including: • Simple Harmonic Motion • Mass on spring / Simple pendulum • Wave Motion • Waves on a string / Sound Waves • Doppler Effect • Interference Effects • Standing Waves / Beats • Light, Index of refraction • Reflection, Refraction • Lenses

  2. 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!

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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

  8. Sinusoidal Wave snapshot k=2π/λ

  9. Sinusoidal Wave at a point in space ω=2π/T

  10. 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

  11. Standing Waves

  12. Beats

  13. 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.

  14. 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.

  15. Total Internal Reflection

  16. 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

  17. Images in a flat mirror

  18. The Thin Lens Equation
