5 Written questions

5 Matching questions

  1. 2 relationships for waves
  2. constructive interference
  3. wave
  4. amplitude
  5. medium
  1. a 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)
  2. b when waves combine to a larger amplitude
  3. c
    for transverse waves: the distance between the resting point (or equilibrium) to the crest or trough
  4. d any substance that a wave moves through
  5. e a disturbance that transfers energy from one place to another

5 Multiple choice questions

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

  2. lowest point (valley) of a wave
  3. Radio, infrared (IR), light
  4. the spreading out of waves through an opening or around the edges of an obstacle
  5. Sound, ocean waves, earthquakes

5 True/False questions

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

          

  2. mechanical wavewaves that transfer energy through matter

          

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

          

  4. destructive interferencewhen waves cancel each other out

          

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