Across
  1. 2. The region in a longitudinal wave where particles are pushed together
  2. 3. Type of wave where oscillations are parallel to direction of energy transfer
  3. 8. Change in direction of waves when they change speed moving between media
  4. 11. A measurable effect of increased amplitude in sound waves
  5. 12. The formula linking wave speed, frequency and wavelength
  6. 14. The bouncing back of waves from a surface
  7. 15. The number of complete wave cycles passing a point per second
Down
  1. 1. The time taken for one full cycle of a wave to pass a point
  2. 4. Type of wave where oscillations are perpendicular to direction of energy transfer
  3. 5. The maximum displacement of particles from their rest position in a wave
  4. 6. Unit of frequency, equal to one cycle per second
  5. 7. The total length of one full wave cycle (crest to crest or compression to compression)
  6. 9. The region in a longitudinal wave where particles are more spread out
  7. 10. The part of the ear that vibrates in response to sound waves
  8. 13. Spreading out of waves after passing through a gap or around an obstacle
