  1. a when waves combine to a larger amplitude
  2. b mirror (light waves), echo (sound waves), RADAR (radio waves)
  3. c
    highest point (peak) of a wave
  4. d light will bend around a lampshade; sounds can be heard even if you are hiding behind something
  5. e the bending of a wave as it enters a new medium at an angle other than 90 degrees

5 Multiple choice questions

  1. any substance that a wave moves through

  2. the distance from one wave crest to the very next crest. (This may also be measured from trough to trough.)
  3. when waves cancel each other out
  4. Sound, ocean waves, earthquakes

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