  1. interference
  2. reflection examples
  3. mechanical wave
  4. Examples of EM Waves
  5. frequency
  1. a 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
  2. b mirror (light waves), echo (sound waves), RADAR (radio waves)
  3. c Radio, infrared (IR), light
  4. d the meeting and combining of waves
  5. e waves that transfer energy through matter

5 Multiple choice questions

  1. the spreading out of waves through an opening or around the edges of an obstacle
  2. Sound, ocean waves, earthquakes
  3. light will bend around a lampshade; sounds can be heard even if you are hiding behind something
  4. the bending of a wave as it enters a new medium at an angle other than 90 degrees
  5. Infrared

5 True/False questions

  1. EM Waveelectromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium - DOES NOT REQUIRE A MEDIUM)


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


  3. wavea disturbance that transfers energy from one place to another


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


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