  1. 4. The number of cycles.
  2. 5. The maximum distance that the particle of the wave's medium vibrate from their rest position
  3. 9. A wave in which the particles of the medium vibrates parallel to the direction of wave motion.
  4. 10. The combination of two or more waves that results in a single wave
  5. 13. The time required for corresponding point on consecutive wave to pass a given point.
  6. 15. A phenomenon that occurs when two objects naturally vibrate at the same frequency.
  7. 16. A wave that requires a medium through which to travel.

  1. 1. A wave consisting of changing electric and magnetic fields.
  2. 2. A longitudinal wave that is caused by vibrations and that travels through a material medium.
  3. 3. Sound navigation and ranging
  4. 6. A unit of frequency equal to one cycle per second.
  5. 7. A disturbance that transfers energy from one place to another
  6. 8. A physical environment in which phenomena occur.
  7. 11. A wave in which the particles of the median move perpendicular to the direction the wave is traveling
  8. 12. An observed change in frequency of a wave when the source is moving.
