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