5 Matching questions

  1. Examples of EM Waves
  2. mechanical wave
  3. amplitude
  4. refraction
  5. reflection examples
  1. a Radio, infrared (IR), light
  2. b mirror (light waves), echo (sound waves), RADAR (radio waves)
  3. c
    for transverse waves: the distance between the resting point (or equilibrium) to the crest or trough
  4. d the bending of a wave as it enters a new medium at an angle other than 90 degrees
  5. e waves that transfer energy through matter

5 Multiple choice questions

  1. the meeting and combining of waves
  2. light will bend around a lampshade; sounds can be heard even if you are hiding behind something

  3. lowest point (valley) of a wave

  4. highest point (peak) of a wave
  5. 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 True/False questions

  1. waveelectromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium)


  2. constructive interferencewhen waves combine to a larger amplitude


  3. destructive interferencewhen waves cancel each other out


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


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