Across
  1. 5. 2 or more waves arrive at the same point at the same time and combine to make a single wave
  2. 7. the medium moves at right angles in the direction of the wave
  3. 9. A disturbance that carries energy from one place to another is called a
  4. 14. wave that requires no medium and travels in between particles
  5. 16. particles are close together
  6. 17. height of a wavelength measured from crest to trough
Down
  1. 1. number of waves that go past a point in one secon
  2. 2. distance between one point on a wave and the exact same point on the next wave
  3. 3. wave that requires a medium to travel from one particle to the next particle of a medium
  4. 4. particles are spread apart
  5. 6. takes place when a wave passes from one medium to another at an angle
  6. 8. results when a wave passes through a hole or a barrier and spreads out
  7. 10. the medium moves back and forth in the same direction as the wave
  8. 11. material in which a wave travels through
  9. 12. when a wave hits an obhect it cannot pass through or reaches the boundar of a medium
  10. 13. phenomenon in whcih there is a change in the frequency due to motion of the wave source or wave observer
  11. 15. space where there is no matter
