  1. interference
  2. diffraction
  3. frequency
  4. Examples of mechanical waves
  5. EM Wave
  1. a Sound, ocean waves, earthquakes
  2. b the meeting and combining of waves
  3. c the spreading out of waves through an opening or around the edges of an obstacle
  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. any substance that a wave moves through
  2. a straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)

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

  4. lowest point (valley) of a wave
  5. the bouncing back of a wave as it strikes a barrier
