Across
  1. 2. / moves the particles in a medium parallel to the direction of the wave
  2. 3. / wave that can travel through empty space
  3. 5. / material in which a wave travels
  4. 8. / regions of a longitudinal wave where the particles are farthest
  5. 9. / the transfer of energy from a wave to a medium
  6. 11. / when a wave hits an object and bounces off of it
  7. 13. / when a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
  8. 16. / the disturbance is perpendicular to the direction of the wave
  9. 17. / increase in amplitude that occurs when an object vibrates at its natural frequency absorbs energy from nearby objects vibrating at the same frequency
  10. 18. / regions of a longitudinal wave where the particles are closest
  11. 19. / bending and spreading of waves around an obstacle
  12. 20. / highest point on a wave
Down
  1. 1. / when a wave travels through a medium or into a new medium
  2. 4. / maximum distance particles in mediums moves from their rest positions
  3. 6. / can only travel through matter
  4. 7. / # of wavelengths that pass a second
  5. 10. / distance from one point on a wave to the next nearest
  6. 12. / a disturbance that transfers energy from one place to the next
  7. 14. / when waves overlap and form a new wave
  8. 15. / lowest point on a wave
