Oscillations
Mathematical Anatomy of Simple Harmonic Graph:

  • x-axis = time axis
  • y-axis = displacement
  • Key features:
    • Amplitude
    • Temporal period
    • Temporal frequency
    • Angular frequency
      Graph of a sinusoidal oscillation. Examples include:
  • Mass on spring
  • Pendulum (swing)
    Damped vs. Forced Oscillation:
  • Damped Oscillation Examples:
    • Swing without moving legs
    • Pendulum moving until it stops
  • Forced Oscillation Examples:
    • Moving legs on swing to keep swinging
    • Pushing a person on swing

Waves
Types of physical waves:

  • Mechanical waves
  • Electromagnetic waves
    Propagation in Medium:
  • Transverse waves (light, surface waves, rope wave, etc.)
  • Longitudinal waves (sound waves, seismic waves, etc.)
    Mathematical Anatomy of Waves:
  • Key features:
    • Amplitude
    • Speed of wave
    • Wavelength (spatial period)
    • Frequency
    • Period

Key Characteristics:

  • Amplitude = height of graph; relates to strength, loudness
  • Frequency = how scrunched up; relates to pitch
