5 Multiple choice questions

  1. the bouncing back of a wave as it strikes a barrier
  2. Infrared
  3. mirror (light waves), echo (sound waves), RADAR (radio waves)
  4. waves that transfer energy through matter
  5. a straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)

5 True/False questions

  1. destructive interferencewhen waves cancel each other out


  2. mediumany substance that a wave moves through


  3. EM Waveelectromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium - DOES NOT REQUIRE A MEDIUM)


  4. wavelengtha disturbance that transfers energy from one place to another


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