waves

• Transverse Waves


  • Single disturbance of pulse transfers but not mass through space
  • Succession of transverse pulses
  • Direction of movement of particles is perpendicular to the direction of propagation of the wave
• Particles move up and down (perpendicular to the direction of propagation)
• In-Phase


  Points on a wave that are at similar times (same direction)
• Out of Phase


  Points on a wave that are not at similar positions
• Longitudinal


  Particles vibrate in the direction of wave travel
• How sound waves travel

  1. Compression

  2. Rarefaction
• Compression is where the particles are close together
• Rarefaction is where the particles are far apart
• Particle movement is parallel to the direction of wave propagation
• Particles move left and right as the wave passes
• Longitudinal waves are sound waves
