5 Written questions

5 Matching questions

  1. constructive interference
  2. Examples of EM Waves
  3. diffraction
  4. Waves caused by vibrations of atoms
  5. wavelength
  1. a when waves combine to a larger amplitude
  2. b
    the distance from one wave crest to the very next crest. (This may also be measured from trough to trough.)
  3. c Infrared
  4. d the spreading out of waves through an opening or around the edges of an obstacle
  5. e Radio, infrared (IR), light

5 Multiple choice questions

  1. mirror (light waves), echo (sound waves), RADAR (radio waves)
  2. Sound, ocean waves, earthquakes
  3. 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
  4. the bending of a wave as it enters a new medium at an angle other than 90 degrees
  5. when waves cancel each other out

5 True/False questions

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

          

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

          

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

          

  4. 2 relationships for wavesRadio, infrared (IR), light

          

  5. mediumany substance that a wave moves through
