5 Matching Questions

  1. EM Wave
  2. crest
  3. interference
  4. Examples of mechanical waves
  5. frequency
  1. a
    highest point (peak) of a wave
  2. b the meeting and combining of waves
  3. c Sound, ocean waves, earthquakes
  4. d the number of waves passing a fixed point in a certain amount of time; it is based partly on wavelength (longer wavelengths take a longer time to pass) and partly on the speed the wave travels
  5. e electromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium)

5 Multiple Choice Questions


  1. the distance from one wave crest to the very next crest. (This may also be measured from trough to trough.)
  2. light will bend around a lampshade; sounds can be heard even if you are hiding behind something
  3. a straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)
  4. the spreading out of waves through an opening or around the edges of an obstacle
  5. mirror (light waves), echo (sound waves), RADAR (radio waves)
