5 Matching questions

  1. medium
  2. reflection
  3. trough
  4. EM Wave
  5. constructive interference
  1. a electromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium)
  2. b
    lowest point (valley) of a wave
  3. c the bouncing back of a wave as it strikes a barrier
  4. d when waves combine to a larger amplitude
  5. e any substance that a wave moves through

5 Multiple choice questions

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

5 True/False questions

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

          

  2. Examples of mechanical wavesSound, ocean waves, earthquakes

          

  3. crest
    lowest point (valley) of a wave

          

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

          

  5. Examples of EM WavesSound, ocean waves, earthquakes
