  1. a a disturbance that transfers energy from one place to another
  2. b
    highest point (peak) of a wave
  3. c the meeting and combining of waves
  4. d Sound, ocean waves, earthquakes
  5. e the bouncing back of a wave as it strikes a barrier

5 Multiple choice questions

  1. when waves combine to a larger amplitude
  2. electromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium)
  3. waves that transfer energy through matter

  4. lowest point (valley) of a wave

  5. for transverse waves: the distance between the resting point (or equilibrium) to the crest or trough

5 True/False questions

  1. wavelength
    the distance from one wave crest to the very next crest. (This may also be measured from trough to trough.)


  2. destructive interferencewhen waves combine to a larger amplitude


  3. Examples of EM WavesRadio, infrared (IR), light


  4. diffractionthe bending of a wave as it enters a new medium at an angle other than 90 degrees


  5. reflection examplesa straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)
