  1. 3. the highest point of a wave
  2. 5. the distance from any point on a wave to an identical point on the next wave
  3. 10. a change in the dirction of a wave when the wave finds an obstacle or an edge, such as an opening
  4. 13. the bending of a wave front as the wave front passes between two substances in which the speed of the wave differs
  5. 14. the time that it takes a complete cycle or wave oscillation to occur
  6. 16. the max distance that the particles of a wave's medium vibrate from their rest position
  7. 17. the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
  8. 18. a wave that requires a medium through which to travel
  9. 19. a wave that consists of magnetic fields which radiate outward at the speed of light
Down
  1. 1. a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
  2. 2. a wave in which the particles of the medium vibrate parallel to the direction of wave motion
  3. 4. a superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves
  4. 6. an observed change in the frequency of a wave when the source or observer is moving
  5. 7. a physical environment in which phenomena occurs
  6. 8. a pattern of vibration that simulates a wave that is standing still
  7. 9. the combination of two or more waves that result in a single wave
  8. 11. the number of cycles or vibrations per unit of time; also the number of waves produced in a given amount of time
  9. 12. the lowest point of a wave
  10. 15. a superposition of two or more waves that produces an intensity equal to the difference of the intensities of the individual waves
