Wave properties

5. The change in direction of a wave that occurs as the wave changes speed when moving through one medium to another.
6. The regions on a longitudinal wave that are farthest apart.
7. a wave in which the disturbance is perpendicular to the direction the wave travels.
10. A wave that can travel both through empty space and through matter.
11. The number of wavelengths that pass by in a number of seconds.
13. highest point on a wave.
15. The region on a longitudinal wave that is close together.
17. The passage of light through an object.
19. When a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence.
20. The bouncing of a wave off a surface.

1. A wave that can travel only through matter.
2. When waves that overlap combine, forming a new wave.
3. makes the particles in a medium move parallel to the direction that the wave travels.
4. The change in direction of a wave when it travels by the edge of an object or through an opening.
8. lowest point on a wave.
9. A material in which a wave travels.
12. The distance from one point on a wave to the same point on the next.
14. The transfer of energy by a wave to the medium through which it travels.
16. The maximum distance that the wave moves from its rest position.
18. A disturbance that transfers energy from one place to another without transferring matter.
