  1. reflection
  2. EM Wave
  3. wave
  4. Examples of mechanical waves
  5. Examples of EM Waves
  1. a Radio, infrared (IR), light
  2. b the bouncing back of a wave as it strikes a barrier
  3. c a disturbance that transfers energy from one place to another
  4. d electromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium - DOES NOT REQUIRE A MEDIUM)
  5. e Sound, ocean waves, earthquakes

5 Multiple choice questions

  1. 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. Infrared
  3. mirror (light waves), echo (sound waves), RADAR (radio waves)
  4. the spreading out of waves through an opening or around the edges of an obstacle
  5. any substance that a wave moves through

5 True/False questions

  1. interferencethe 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. frequencyany substance that a wave moves through

          

  3. amplitudeany substance that a wave moves through

          

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

          

  5. mechanical waveelectromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium - DOES NOT REQUIRE A MEDIUM)
