Ultrasound problem 17


Sounds are made by vibrating objects. A certain object vibrates but a person nearby cannot hear any sound. Which statement might explain why nothing is heard.


  • The amplitude of the sound waves is too large.

  • The frequency of the vibration is too high.

  • The sound waves are transverse.

  • The speed of the sound waves is too high.
