Across
  1. 3. The bending of a wave as it enters a new medium at an angle.
  2. 4. A wave in which particles move parallel to the direction of the wave.
  3. 6. The time it takes for one complete wave cycle to pass a point.
  4. 8. A disturbance that transfers energy through matter or space.
  5. 9. The number of wave cycles that pass a point in one second.
  6. 12. The maximum displacement from the rest position in a wave.
  7. 13. A wave in which the particles move perpendicular to the direction of the wave.
  8. 14. A transparent object that refracts light rays to form an image.
  9. 15. The combination of two or more waves resulting in a new wave pattern.
Down
  1. 1. The bouncing back of a wave when it hits a surface it cannot pass through.
  2. 2. Type of interference where wave amplitudes add together.
  3. 5. The spreading out of waves when they pass through a opening or around obstacles.
  4. 7. A lens that is thicker in the center than at the edges and converges light rays.
  5. 10. Type of interference where wave amplitudes cancel each other out.
  6. 11. The distance between two consecutive crests or troughs in a wave.
