Across
  1. 3. When a wave is reflected, the angle of reflection is equal to the angle of incidence
  2. 4. The highest point on a transverse wave
  3. 5. The maximum distance the wave moves from the rest position
  4. 6. The change in direction of a wave when it travels from one medium to another
  5. 8. A material in which the wave travels through
  6. 10. The distance from one crest to to the next crest or one trough to the next trough
  7. 11. The lowest point on a transverse wave
  8. 12. The particles move parallel to the direction the wave travels
  9. 14. Mechanical waves that travel within and on Earth's surface
  10. 15. The disturbance is perpendicular to the direction the wave travels
  11. 16. The unit of measurement for frequency
  12. 17. The change in direction of a wave when it travels through an opening
  13. 18. A disturbance that transfers energy
Down
  1. 1. The number of wavelengths that pass by a point each second
  2. 2. A wave that can travel through empty space and through matter
  3. 5. The transfer of energy by a wave to the medium
  4. 7. Calculated by multiplying frequency by wavelength
  5. 9. A wave that can only travel through matter
  6. 13. A wave bouncing off a surface
  7. 14. Longitudinal waves that travel in solids, liquids, and gasses
