Across
  1. 6. Waves that require a medium to go through
  2. 10. Waves that transfer energy horizontally in their medium, they require a medium
  3. 12. The bouncing back of a wave when it cannot pass through a surface
  4. 13. The unit for frequency, equal to one cycle per second
  5. 15. The biological process of using sound waves to find objects, animals such as bats use this
  6. 17. How tall the wave is on one side of the equilibrium
  7. 18. How high or low the noise of the wave is depending on frequency
Down
  1. 1. A unit used to compare the loudness of sound
  2. 2. Highest point of a wave
  3. 3. The distance between to crest or troughs
  4. 4. Waves that move energy perpendicular to the equilibrium, not all waves require a medium
  5. 5. Slower than the speed of sound
  6. 7. Faster than the speed of sound
  7. 8. How many wave peaks or troughs pass a given point in a certain time
  8. 9. A manmade instrument that creates sound waves to produce a picture of where things are located
  9. 11. A unit of motion that repeats
  10. 14. Material through which a wave has to travel through which is a solid, liquid or gas
  11. 16. Lowest point of a wave
