Across
- 3. waves bending around an obstacle
- 6. the highest point of a wave
- 8. a wave vibrating in the direction of propagation.
- 10. the lowest point of a wave
- 14. the full range of electromagnetic radiation
- 15. the distance between one crest and another crest, or between one trough and another trough
Down
- 1. the bending of a wave once a it passes from one medium to another
- 2. a wave that travels along the surface of a medium, rather than through it.
- 4. the amount of waves that pass a certain point in a certain time
- 5. when two waves meet and alter each other's amplitudes
- 7. the material a wave travels through
- 9. the height of a wave
- 11. the change in direction of a wave once it reaches a boundary
- 12. a disturbance that travels through a medium, like water, air, or a rope.
- 13. how high or low a sound wave is, determined by its frequency
