Waves transfer energy & momentum from one point to another without transferring any matter  between them.

Types of waves:

  • Mechanical (waves are made up of particles vibrating e.g. sound)
  • Electromagnetic (waves are made up of oscillating electric & magnetic fields e.g. light)

Mechanical waves require a substance but electromagnetic waves do not. Therefore mechanical waves cannot travel through a vacuum but electromagentic waves can.

  • Transverse: displacement is at right angles (perpendicular) to the direction of the wave.
  • Longitudinal: displacement is parallel to the direction of the wave
  • Progressive: waves…
