Across
  1. 2. need a medium ex. ripples on water
  2. 5. The time required for two successive wave crests to pass a fixed point
  3. 7. the change in direction of a wave passing from one medium to another caused by its change in speed
  4. 8. radio, microwave, infered, vissible light, ultraviolet, x-ray, Gamma
  5. 11. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
  6. 13. the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated
  7. 16. the change in frequency of a wave in relation to an observer who is moving relative to the wave source
Down
  1. 1. wave is perpendicular to particle motion
  2. 3. longitudinal+transversal
  3. 4. wave motion is parallel to particle motion
  4. 6. the lowest point the medium sinks to
  5. 9. the distance between two peaks in a wave
  6. 10. do not need a medium ex. light
  7. 12. a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge
  8. 14. the point on a wave with the maximum value of upward displacement within a cycle
  9. 15. the number of times an event occurs per unit of time
