    Types of Waves

    Longitudinal Waves
    • Definition: Waves in which the particles of the medium vibrate back and forth along the direction of propagation.
    • Characteristics:
      • Compressions: particles are close together
      • Rarefactions: particles are far apart
      • Particles oscillate along the direction of wave propagation
    • Examples:
      • Sound waves in a gas
      • Seismic P-waves (primary waves) in the Earth's interior
    Transverse Waves
    • Definition: Waves in which the particles of the medium vibrate perpendicular to the direction of propagation.
    • Characteristics:
      • Particles oscillate in a direction perpendicular to the wave propagation
      • Crests: highest points of the wave
      • Troughs: lowest points of the wave
    • Examples:
      • Water waves (ripples) on a lake
      • Light waves (electromagnetic waves)
      • Seismic S-waves (shear waves) in the Earth's interior

    Types of Waves

    Longitudinal Waves

    • Particles of the medium vibrate back and forth along the direction of propagation.
    • Characterized by compressions (particles close together) and rarefactions (particles far apart).
    • Particles oscillate along the direction of wave propagation.
    • Examples include sound waves in a gas and seismic P-waves (primary waves) in the Earth's interior.

    Transverse Waves

    • Particles of the medium vibrate perpendicular to the direction of propagation.
    • Particles oscillate in a direction perpendicular to the wave propagation.
    • Waves have crests (highest points) and troughs (lowest points).
    • Examples include water waves (ripples) on a lake, light waves (electromagnetic waves), and seismic S-waves (shear waves) in the Earth's interior.
