Across
  1. 2. causes medium to move perpendicular of wave direction
  2. 3. how often a wave occurs
  3. 4. bending of light as it passes from one medium to another
  4. 8. causes medium to move parallel to direction of the wave
  5. 12. electrical and magnetic forces produced by an electric current
  6. 13. rate that a wave travels through a medium
  7. 15. two or more waves overlap resulting in smaller amplitude
Down
  1. 1. two or more waves align and their crests and troughs coincide resulting with a wave with a larger amplitude
  2. 5. maximum displacement or distance moved by a point on a wave
  3. 6. distance between two corresponding points on a wave
  4. 7. the range of all types of EM radiation
  5. 9. spreading of waves as they pass through an opening which causes them to bend from straight-line path
  6. 10. substance or material that a wave or energy can propogate
  7. 11. return of light or sound waves from a surface
  8. 14. change in frequency of a wave
