Across
  1. 2. Interference: The interaction of two or more waves overlapping in a medium.
  2. 6. Sound waves with frequencies above human hearing (above 20,000 Hz).
  3. 7. Speeds exceeding Mach 5, much faster than the speed of sound.
  4. 9. A region in a longitudinal wave where particles are closest together.
  5. 11. A region in a longitudinal wave where particles are spread apart.
  6. 13. Sound waves with frequencies below human hearing (below 20 Hz).
  7. 15. Whole number multiples of a fundamental frequency in a vibrating system.
  8. 17. Interference: When waves combine to reduce or cancel out their amplitudes.
  9. 18. A unit measuring the intensity of sound on a logarithmic scale.
  10. 19. The perceived frequency of a sound, determining how high or low it is.
  11. 20. A point in a standing wave where there is no movement.
  12. 21. The ratio of an object's speed to the speed of sound in a given medium.

  1. 1. Frequency: The frequency at which an object naturally vibrates when disturbed.
  2. 3. Effect: The change in frequency or pitch of a wave due to the motion of the source or observer.
  3. 4. Wave: A wave pattern that appears stationary due to the interference of two opposite-traveling waves.
  4. 5. Superposition: The principle that the total displacement at any point is the sum of individual wave displacements.
  5. 8. Interference: When waves combine to create a wave with greater amplitude.
  6. 10. The amplification of vibrations when an object is exposed to its natural frequency.
  7. 12. A point in a standing wave with maximum displacement.
  8. 14. Vibration: When an object is made to vibrate by an external force at a specific frequency.
  9. 16. A periodic variation in sound intensity caused by the interference of two sound waves with slightly different frequencies.
