transverse and longitudinal waves

• What do all types of waves transfer?

  Energy from one place to another
• What type of energy do ripples transfer?

  Kinetic energy
• What type of energy do sound waves transfer?

  Sound energy
• How do oscillations in transverse waves move?

  Perpendicular to the direction of energy transfer
• What is the term used for the movements in waves?

  Oscillations
• What does the term 'perpendicular' mean in the context of waves?

  At right angles
• How do oscillations in longitudinal waves move?

  Parallel to the direction of energy transfer
• What are the regions where air particles are close together called?

  Compressions
• What are the regions where air particles are spaced out called?

  Rarifications
• What is a key difference between transverse and longitudinal waves?

  Longitudinal waves require a medium to travel
• Can all transverse waves travel without a medium?

  No, not all transverse waves require a medium
• What is a crucial fact about waves in relation to the medium?

  The wave travels, not the medium
• How can you visualize transverse waves using a slinky?

  By showing oscillations up and down
• How can you visualize longitudinal waves using a slinky?

  By showing oscillations from side to side
• What does the red dot represent in the slinky demonstration?

  A water molecule or air particle
• What happens to the red dot in the slinky demonstration?

  It oscillates but does not travel
• What are the key features of transverse waves?

  • Oscillations are perpendicular to energy transfer
  • Example: Ripples on water
  • Transfer kinetic energy
• What are the key features of longitudinal waves?

  • Oscillations are parallel to energy transfer
  • Example: Sound waves in air
  • Require a medium to travel
• What is the difference in energy transfer between transverse and longitudinal waves?

  • Transverse: Energy transfer is sideways
  • Longitudinal: Energy transfer is along the direction of oscillation
