1. waves

   • basic wave properties - A wave motions a means of transferring energy from place to place, without transferring matter.
     • transverse waves
       • when transverse waves are moving in a medium the particles are oscillating at right angles to the direction of travel e.g/ light waves, water waves
     • Longitudinal waves
       • when longitudinal waves are moving in a medium the particles are oscillating parallel to the direction on which energy is being transferred. e.g/sound waves
