5 Matching questions

  1. amplitude
  2. mechanical wave
  3. frequency
  4. medium
  5. trough
  1. a waves that transfer energy through matter
  2. b
    lowest point (valley) of a wave
  3. c any substance that a wave moves through
  4. d
    for transverse waves: the distance between the resting point (or equilibrium) to the crest or trough
  5. e 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 Multiple choice questions

  1. highest point (peak) of a wave
  2. electromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium)
  3. 1) 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)
  4. the spreading out of waves through an opening or around the edges of an obstacle
  5. when waves cancel each other out

5 True/False questions

  1. refraction examplesmirror (light waves), echo (sound waves), RADAR (radio waves)


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


  3. reflectionthe bouncing back of a wave as it strikes a barrier


  4. Examples of mechanical wavesRadio, infrared (IR), light


  5. diffraction exampleslight will bend around a lampshade; sounds can be heard even if you are hiding behind something
