Across
  1. 3. perpendicular to the direction of the wave
  2. 4. highest point of a wave
  3. 9. When an object causes a wave to change direction and bend around it
  4. 11. the number of wavelengths that pass a fixed point each second
  5. 12. repeating disturbances or movement that transfers energy through matter or space
  6. 16. particles in a longitudinal wave are closest together
  7. 17. when light bounces off a surface
  8. 19. the size of a disturbance from a wave
  9. 20. parallel with direction
Down
  1. 1. a place in a wave where the molecules are far apart
  2. 2. when two or more waves overlap and combine to form a new wave
  3. 5. process by which an object is made to vibrate by absorbing energy at its natural frequencies
  4. 6. Wave bends due to change of speed
  5. 7. lowest point of a wave
  6. 8. the distance between one point on a wave and the nearest point just like it
  7. 10. waves that can travel through earth and along the surface
  8. 13. The amount of time it takes one wavelength to pass a point
  9. 14. the matter through which mechanical waves travel
  10. 15. What type of waves can be either transverse or compressional
  11. 18. Forms when waves equal in wavelength and amplitude
