3.2 describe longitudinal and transverse waves in ropes, springs and water where appropriate

  • Waves move up and down but energy travels forward
  • Waves move back and forth but energy travels forward

Transverse waves – Waves  that travel in a direction perpendicular to the direction of the vibration. For example, light and water waves

  • Transverse waves can be shown on a rope by moving them up and down (wave crest and trough moves up and down)
  • Direction of the vibration emit as you shake the rope
  • The direction of wave motion is perpendicular to the direction of the wave (forwards)



Latitudinal waves – Waves that travel in a direction parallel to the direction of vibration – eg. sound waves

  • Latitudinal waves are shown by the push/pull of a spring/ slinky as it compresses and expands. Notice the coils move back and forth
  • Direction of wave motion is parallel to direction of vibrationf-d-c8cbeef7863716346317e25d339173f178337595e69b67fbd6e0d4ce+IMAGE_THUMB_POSTCARD+IMAGE_THUMB_POSTCARD.png\
