Across
  1. 5. an up-and-down or back-and-forth motion
  2. 10. one-half the distance between a wave's high point and low point
  3. 11. the transfer of energy from a wave to matter as the wave passes through it
  4. 13. waves that move through matter
  5. 14. when waves bounce off a surface
  6. 16. our perception of sound wave frequency
  7. 17. states that waves get reflected at the same angle as the angle that it moved toward the barrier
  8. 21. waves that move through vacuums
  9. 22. measured from a point on one wave to the same point on the next wave
  10. 23. combine to form a larger wave
Down
  1. 1. oscillate in the same direction as it moves
  2. 2. number of waves that pass a fixed point in a given unit of time
  3. 3. cancel each other out
  4. 4. bending of waves as they travel through different mediums
  5. 6. the wavelength and frequency range of electromagnetic waves
  6. 7. used to measure the loudness, or intensity of sound
  7. 8. bending of waves around a barrier past small openings
  8. 9. oscillations that carry energy
  9. 12. the time it takes a wave to move from one point to another
  10. 15. a result of waves colliding with each other
  11. 18. oscillate perpendicular to the direction of motion
  12. 19. how much energy a sound wave carries
  13. 20. space that has no matter in it
