Across
  1. 3. the time taken for a wave to complete its cycle.
  2. 5. the length of one wave cycle. it is the distance of one compression to another.
  3. 6. height of a wave. it is usually measured in meters.
  4. 7. mechanical waves that are caused by a vibration. it can be heard by our ears.
  5. 8. energy that is given off by things like stars, light bulbs, lasers, and hot objects.
  6. 9. a wave where the disturbance moves perpendicular to the direction of the wave.
Down
  1. 1. a wave where the disturbance travels in the same direction as the wave.
  2. 2. waves produced by a mechanical movement or vibrating objects. it transfers energy through a series of collisions.
  3. 4. the number of times a wave cycles in one second. it it measured in hertz (Hz).
  4. 5. a regular pattern of motion created by a vibratory disturbance. waves travel energy but not matter.
