waves

• waves carry energy from one place to another with no transverse of matter

  
• list some examples of waves

  microwaves, sound and light

  
• Define a transverse wave.


  oscillations are perpendicular to the direction of energy transferred

  
• Define a longitudinal wave.

  oscillations are pararell to the direction of the energy transferred

  A) rarefaction

  B) compression

  C) wavelength

  
• wavelength is measured in 


  meters
• wavelength is the


  distance from one point on a wave to the same point on the next wave

  
• amplitude is measured in


  meters

  
• amplitude is the

  waves displacement of a point on a wave from its undisturbed position

  
• frequency is measured in


  hertz
• frequency is the 


  number of waves passing a point per second

  
• period is measured in 


  seconds

  
• period is the 


  time it takes to produce one complete wave

  
• longitudinal have properties which are

  compression and rarefaction
