  • Waves
    • Transfer energy from one place to another without transferring matter
    • Transverse
      • The oscillations (vibrations) are PERPENDICULAR (at 90 degrees) to the DIRECTION of energy transfer.
      • Most waves are transverse
        • Electromagnetic Waves e.g light
        • Ripples and waves in water
      • A wave on a string
    • Longitudinal
      • The oscillations are PARALLEL to the DIRECTION of energy transfer.
        • Sound waves in air, ultrasound
        • Shock waves e.g some seismic waves
    • Wave Speed
      • Frequency multiplied by wave length
