  3. wave
  4. destructive interference
  5. reflection
  1. a when waves cancel each other out
  2. b the bouncing back of a wave as it strikes a barrier
  3. c a disturbance that transfers energy from one place to another
  4. d a straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)
  5. e mirror (light waves), echo (sound waves), RADAR (radio waves)

5 Multiple choice questions

  1. Infrared
  2. the spreading out of waves through an opening or around the edges of an obstacle
  3. the bending of a wave as it enters a new medium at an angle other than 90 degrees
  4. any substance that a wave moves through

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

5 True/False questions

  1. interferencethe meeting and combining of waves

          

  2. EM Wavea disturbance that transfers energy from one place to another

          

  3. frequencya disturbance that transfers energy from one place to another

          

  4. 2 relationships for waves1) speed and frequency = directly proportional
    (as speed goes up, frequency goes up)
    2) wavelength and frequency = inversely proportional
    (as wavelength gets longer, frequency goes down)

          

  5. mechanical wavewaves that transfer energy through matter
