WAVES
- Cause by vibrations or oscillations.
- Transport energy without permanently displacing the medium.
- Can either be a Mechanical waves which require a medium to travel eg. Sound wave or Electromagnetic waves which do not require a medium to travel.
There are two types of waves:
- Transverse Waves:
The vibration of the particles of the medium is perpendicular (up and down ) to the motion of the wave. eg. Water waves, light waves,rope waves and waves on springs. (MC,MG 1-1)
- Longitudinal Waves:
The vibration of the particles of the medium is along the same direction (parallel) as the motion of the wave. eg.Waves on springs and sound waves.
