  1. 2 relationships for waves
  2. Examples of mechanical waves
  3. refraction examples
  4. trough
  5. constructive interference
  1. a a straw looks "broken" when you look at it in a glass of water (because the light bends when it enters the water)
  2. b
    lowest point (valley) of a wave
  3. c 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. d Sound, ocean waves, earthquakes
  5. e when waves combine to a larger amplitude

5 Multiple Choice Questions

  1. highest point (peak) of a wave
  2. light will bend around a lampshade; sounds can be heard even if you are hiding behind something
  3. when waves cancel each other out

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

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

5 True/False Questions

  1. Examples of EM WavesRadio, infrared (IR), light


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


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


  4. EM Wavea disturbance that transfers energy from one place to another


  5. frequency
    highest point (peak) of a wave
