  5. reflection
  1. a light will bend around a lampshade; sounds can be heard even if you are hiding behind something
  2. b the bending of a wave as it enters a new medium at an angle other than 90 degrees
  3. c the bouncing back of a wave as it strikes a barrier
  4. d when waves cancel each other out
  5. e Radio, infrared (IR), light

5 Multiple Choice Questions

  1. electromagnetic wave; moves energy through space (sometimes empty space, sometimes through a medium)
  2. when waves combine to a larger amplitude

  3. highest point (peak) of a wave
  4. 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)

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