wave motion

2. A wave in which the particles of the medium vibrate parallel to the direction of wave motion.
5. Periodic motion where the restoring force is directly proportional to the displacement.
6. A wave in which the particles of the medium vibrate perpendicular to the direction of wave motion.
8. The time taken for one complete cycle of a wave.
11. The maximum displacement of particles from their equilibrium position.
12. The distance between two consecutive points on a wave.
14. The number of wave cycles per second.
15. The lowest point of a wave.

1. The combination of two or more waves that results in a new wave pattern.
3. Force: The force that brings a system back to its equilibrium position after being disturbed.
4. The position of a point on a wave cycle relative to a reference point.
7. The bouncing back of waves from a surface they cannot pass through.
9. The bending of waves around obstacles or through openings.
10. The bending of waves as they pass from one medium to another.
13. The highest point of a wave.
