Across
  1. 4. the location of objects by reflected sound
  2. 9. is a wave in which particles of the medium move in a direction parallel to the direction of the wave.
  3. 10. - it is one of the function of echolocation that helps the animals.
  4. 12. the maximum value of upward displacement within a cycle
  5. 14. – is a wave that is not capable of transmitting energy through a vacuum
  6. 16. is a wave in which particles of the medium move in a direction perpendicular to the direction of the wave’s movement.
  7. 17. - It is a type of animals that uses echolocation.
  8. 19. vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
  9. 20. - Dolphins use echolocation to replace what sense?
Down
  1. 1. an instance of vibrating.
  2. 2. the lowest point below the rest position.
  3. 3. the distance between adjacent identical parts of a wave
  4. 4. a sound or sounds caused by the reflection of sound waves from a surface back to the listener.
  5. 5. - animal that use eccholocation
  6. 6. – is the type of wave that can transmit energy even without any material medium.
  7. 7. the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone
  8. 8. Speed (v) is the distance traveled by a wave per unit time.
  9. 11. the action of compressing or being compressed
  10. 13. is the time taken for one complete cycle of the wave to pass a reference point
  11. 15. The strength or level of sound pressure.
  12. 18. medium a substance in which sound waves travel.
