properties of waves

• describe transverse waves 


  perpendicular oscillations
• give examples of transverse waves 


  em waves, ripples on water and waves on string
• describe longitudinal waves 


  parallel oscillation
• give examples of longitudinal waves

  sound waves and shock waves
• describe amplitude 


  maximum displacement of point on wave from undisturbed position
• describe wavelength 


  distance from point on one wave to same point on adjacent wave
• describe frequency 


  number of waves passing a point each second
