3. Procedures Same as Physics 103 – WebAssign (setup) – Quizzes (5) – Exams (3) – Lab – Final – Powerpoints – Equation sheets

4. Topics Waves and Sound (Ch. 11-12) Thermodynamics (Ch. 13-15) Electricity and Magnetism (Ch. 16-22) Optics (Ch. 23) We’re trying to cover a lot, so we’ll have to skip around some. (almost never do starred sections)

5. General Differences with Physics 103

6. Simple Harmonic Oscillator A little Physics 103 Jumping-off point for Waves

7. Simple Harmonic Oscillator Object subject to restoring force around equilibrium: F = - kx – Force proportional to and opposite displacement – Oscillatory motion around equilibrium – Rate determined by mass m and k – Frictional damping Examples – Block on a spring (car on springs) – Meter stick anchored one end (diving board) – String in guitar (sound wave) – Object bobbing in water – Molecule in crystal lattice

8. Energy in Harmonic Oscillator

9. Harmonic Oscillator Terminology Cycle – One complete oscillation Amplitude – x = -A to x = +A Period – time to make one cycle Frequency – # cycles per second Frequency vs. Period – f = 1/T – T = 1/f
