Unit 15 Waves

4. The distance from crest to crest.
6. the process by which an object is made to vibrate by absorbing energy at its natural frequencies
9. Is the change in direction of a wave that occurs as the wave changes speed when moving from one medium to another.
10. Regions of the longitudinal wave where the particles in the medium are closest together.
11. The Highest point on a wave.
12. Makes the particles in a medium move parallel to the direction that the wave travels.
13. A material in which a wave travels.
14. When a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence.
16. The lowest point on the wave.
17. Change in direction of a wave when it travels by the edge of an object or through an opening.
18. Regions of a longitudinal wave where the particles are farthest apart.
19. the number of wavelengths that pass by a point each second.
20. Bouncing of a wave off of a surface.

1. Is a wave in which the disturbance is perpendicular to the direction of the wave.
2. A wave that can only travel through matter.
3. a disturbance that transfers energy from one place to another without transferring matter
5. Is a wave that can travel through empty space and through matter.
7. The position where the wave is at rest, half way between the crest and trough.
8. Wave is the maximum distance that the wave moves from the rest position.
11. Transverse and longitudinal waves can combine, creates a circular motion
15. Occurs when waves that overlap, combine, forming a new wave.
