Across
  1. 2. Electromagnetic waves with a frequency range detectable by the human eye. Rainbow.
  2. 4. wave that has "bounced" off a boundary/surface
  3. 5. Distance travelled during one oscillation
  4. 7. How fast a wave travels through a medium
  5. 8. A feature of a wave where particles a pressed closer together
  6. 9. Space containing no particles
  7. 10. wave that has passed through a boundary/surface and has "bent" or changed direction
  8. 13. Movement back and forth
  9. 15. Wave oscillates sideways to wave direction (perpendicular)
  10. 16. Wave oscillates forwards/backwards to wave direction (parallel)
  11. 17. Number of oscillations per second, measured in Hertz
Down
  1. 1. Transverse wave that does not need particles to travel (can travel through a vacuum).
  2. 3. A feature of a wave where the particles are spread further apart
  3. 6. A longitudinal wave that travels by particles bumping into each other and rebounding.
  4. 11. When a wave that reaches a boundary/surface and neither completely reflects or refracts. Some energy is transferred to the surface.
  5. 12. A way to transfer energy from one place to another
  6. 14. can't travel through a vacuum
