5 Matching questions

  1. wave
  2. medium
  3. constructive interference
  4. diffraction
  5. Examples of mechanical waves
  1. a Sound, ocean waves, earthquakes
  2. b the spreading out of waves through an opening or around the edges of an obstacle
  3. c a disturbance that transfers energy from one place to another
  4. d when waves combine to a larger amplitude
  5. e any substance that a wave moves through

5 Multiple choice questions


  1. for transverse waves: the distance between the resting point (or equilibrium) to the crest or trough
  2. the bouncing back of a wave as it strikes a barrier

  3. the distance from one wave crest to the very next crest. (This may also be measured from trough to trough.)
  4. the bending of a wave as it enters a new medium at an angle other than 90 degrees
  5. electromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium - DOES NOT REQUIRE A MEDIUM)

5 True/False questions

  1. diffraction examplesa straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)

          

  2. reflection examplesmirror (light waves), echo (sound waves), RADAR (radio waves)

          

  3. refraction examplesa straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)

          

  4. 2 relationships for wavesRadio, infrared (IR), light

          

  5. Waves caused by vibrations of atomsInfrared
