6. Define Amplitude

  • The oscillations are at right angle to the direction of travel.
  • The distance in metres (m) travelled by the wave in one second.
  • It's the maximum displacement from its equilibrium position.
  • An area on a longitudinal wave where particles are furtherest apart.

7. Define Compression

  • An area on a longitudinal wave where the particles are closest together.
  • The oscillations are at right angles to the direction of travel.
  • It's the maximum displacement from its equilibrium position.
  • An area on a longitudinal wave where particles are furtherest apart.

8. Define Rarefaction

  • The oscillations are at right angle to the direction of travel.
  • An area on a longitudinal wave where particles are furtherest apart.
  • An area on a longitudinal wave where particles are closest together.
  • The number of waves produced in one second(s) or the number of waves that pass a point each second.

9. Define Longitudinal Wave

  • It's the maximum displacement from its equilibrium position.
  • The oscillations are parallel to the direction of travel.
  • A regular repetitive motions
  • The oscillations are at right angle to the direction of travel.

10. Define Wavelength

  • A regular repetitive motions
  • An area on a longitudinal wave where particles are furtherest apart.
  • The distance between two adjacent points on a wave that have the same amplitude and are moving in the same direction.
  • It's the maximum displacement from its equilibrium position.

11. Define Wavespeed

  • The distance in metres (m) travelled by the wave in one second.
  • The number of waves produced in one second(s) or the number of waves that pass a point each second.
  • The oscillations are at right angle to the direction of travel.
  • The period of wave, vibration or oscillation is the time required to complete a full cycle. T = 1/f
