Transverse Waves

2:41 Types of Wave
Spec 4.6.1.1
Previous Introduction to Waves Next Longitudinal Waves
  • Transverse waves have vibrations at right angles to the direction of wave travel.
  • Examples include water waves and all electromagnetic waves.
  • A demonstration involves moving a spring up and down to create a transverse wave pattern.
  • Waves transport energy without transporting matter.
  • In a transverse wave, energy is transported in one direction while the medium moves perpendicularly.
  • The vibrations in transverse waves are perpendicular to the energy transport direction.
  • Longitudinal waves have vibrations parallel to the transport direction.
  • Understanding the difference between transverse and longitudinal waves is important for exams.
  • Energy moves along a spring as one part of the wave causes the next part to move.
  • Coils in a spring are connected, transferring kinetic energy from one to the next.
  • The matter transporting the wave does not move along with it.
  • In a spring, the matter returns to its original position after the energy passes.
  • In water waves, objects like leaves bob up and down but do not move with the wave.
