  1. amplitude
  2. medium
  3. interference
  4. reflection examples
  5. frequency
  1. a any substance that a wave moves through
  2. b mirror (light waves), echo (sound waves), RADAR (radio waves)
  3. c 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
  4. d the meeting and combining of waves
  5. e
    for transverse waves: the distance between the resting point (or equilibrium) to the crest or trough

5 Multiple choice questions

  1. when waves cancel each other out
  2. Radio, infrared (IR), light
  3. waves that transfer energy through matter
  4. Infrared
  5. light will bend around a lampshade; sounds can be heard even if you are hiding behind something

5 True/False questions

  1. wavelength
    the distance from one wave crest to the very next crest. (This may also be measured from trough to trough.)

          

  2. refractionthe bending of a wave as it enters a new medium at an angle other than 90 degrees

          

  3. Examples of mechanical wavesSound, ocean waves, earthquakes

          

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

          

  5. reflectionthe bending of a wave as it enters a new medium at an angle other than 90 degrees
