Waves

3. When waves overlap, combine, form a new wave.
5. The highest points on a transverse wave.
10. The regions of a longitudinal wave where the particles in the medium are closest together.
12. Change in direction of a wave when it travels by the edge of an object or through an opening.
13. A material in which a wave travels.
15. A wave that can travel only through matter.
17. When a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence.
19. The distance from one point on a wave to the same point on the next wave.
20. The bouncing of a wave off a surface.

1. A wave in which the disturbance is perpendicular to the direction the wave travels.
2. A wave that can travel through empty space and through matter.
4. The regions of a longitudinal wave where the particles are farthest apart.
6. A disturbance that transfers energy from one place to another without transferring matter.
7. The transfer of energy by a wave to the medium through which it travels.
8. Makes the particles in a medium move parallel to the direction that the wave travels.
9. The change in direction of a wave that occurs as the wave changes speed when moving from one medium to another.
11. The passage of light through an object.
14. The lowest points on a transverse wave.
16. The maximum distance that the wave moves from its rest position.
18. The number of wavelengths that pass by a point each second.
