Across
  1. 1. – f x λ
  2. 3. – Type of wave where particles vibrate perpendicular to wave direction.
  3. 5. – The squeezed part of a longitudinal wave.
  4. 6. – How loud a sound is; depends on amplitude.
  5. 9. – Type of wave where particles vibrate parallel to wave direction.
  6. 10. – Direction of particle vibration in a transverse wave.
  7. 15. – A repeating disturbance that transfers energy through matter or space.
  8. 16. – The stretched or expanded part of a longitudinal wave.
  9. 19. – An imaginary line that connects points on a wave at the same phase.
  10. 20. – Type of wave that needs a medium to travel through (e.g. sound).
  11. 22. – The highest point of a transverse wave.
Down
  1. 2. – A wave that doesn’t need a medium; travels through vacuum.
  2. 4. – Material a mechanical wave moves through.
  3. 7. – Greek letter (λ) used to represent wavelength in equations.
  4. 8. – Height of a wave; linked to energy or loudness.
  5. 11. – Distance between two crests or compressions.
  6. 12. – Time for one wave. Formula: T=1/f
  7. 13. – Unit of frequency, symbol Hz.
  8. 14. – Number of waves per second. Unit = Hertz.
  9. 17. – Direction of particle vibration in a longitudinal wave.
  10. 18. – The lowest point of a transverse wave.
  11. 21. – How high or low a sound seems; depends on frequency.
