Across
- 2. the highest points of a wave,
- 6. a wave in which particles of the medium oscillate in a direction perpendicular to the direction that the wave moves,
- 9. the number of complete cycles of a wave that occur per unit of time,
- 11. a line perpendicular to a surface where a wave hits it,
- 12. the maximum displacement of points on a wave, measured from the rest position,
- 14. the principle stating that the angle of incidence is equal to the angle of reflection,
- 16. a single disturbance that moves through a medium,
- 18. an interference, when two or more waves combine to produce a wave with a larger amplitude,
- 19. the lowest points of a wave,
- 20. a continuous wave that moves from one location to another through a medium,
Down
- 1. an interference, when two or more waves combine to produce a wave with a smaller amplitude,
- 3. a point along a standing wave where the wave has minimal amplitude,
- 4. a wave that remains in a constant position, typically formed by the interference of two travelling waves moving in opposite directions,
- 5. the time taken for one complete cycle of a wave to pass a given point,
- 7. a wave that travel along the area between two different materials, typically seen in water waves,
- 8. the phenomenon that occurs when two or more waves overlap and combine,
- 10. the bending and spreading of waves around obstacles and openings.
- 13. the distance between successive crests, troughs, or identical points of a wave,
- 15. a wave in which particles of the medium move in a direction parallel to the direction that the wave moves,
- 17. the bending of a wave as it passes from one medium to another with different densities,
