Across
  1. 3. the halfway distance between the crest and trough in a transverse wave
  2. 4. the angle of the incoming wave equals the angle of the out going wave
  3. 5. the number of wavelengths that pass by a point each second
  4. 7. the distance between one point on a wave and the nearest point moving at the same speed in the same direction
  5. 10. a compressional wave produced by something vibrating
  6. 11. when you squeeze spring coils together and release them, you create this kind of wave
  7. 12. these are light waves, radio waves or x-rays
  8. 13. something all waves are produced by
  9. 14. a disturbance that carries energy from place to place without transporting matter
Down
  1. 1. the highest point on a transverse wave
  2. 2. this is the bending of waves around an object
  3. 6. this kind of wave causes particles to move back & forth at a right angle in the direction of the wave
  4. 8. the lowest point on a transverse wave
  5. 9. this is the change in direction of a wave when it changes speed as it travels from one material to another
