Transverse Waves

• A transverse wave is one where the particles oscillate perpendicular to the direction of the

  • Propagation of the wave
  • Direction of energy transfer

• Transverse waves show areas of crests(peaks) and troughs

Diagram of a transverse wave

• Examples of transverse waves are:

  • Electromagnetic waves e.g. radio, visible light, UV
  • Vibrations on a guitar string
  • Waves on a rope or slinky

• Transverse waves can be polarised

Exam Hint Questions about transverse waves typically start by asking for a definition, so be ready with a statement about vibrations or oscillations being perpendicular to the travel of the wave.
