Waves

4. a material in which a wave travels
5. the distance from one wave point to another
6. makes the particles in a medium move parallel to the direction that the wave travels.
7. Change in direction of a wave when it travels by the edge of an object or through an opening
10. The passage of light through an object
13. The region of a longitudinal wave where the particles in the medium are closest together
14. The region of a longitudinal wave where particles are farthest apart
15. A wave that can travel only through matter
17. The number of wavelengths by a point each second
19. The bouncing of a wave off an object
20. A wave in which the disturbance is perpendicular to the direction the wave travels.

1. The lowest point in a transverse wave
2. A wave that can travel through empty space and matter
3. the change in a direction of a wave that occurs when the wave changes speed when moving from one medium to the other
8. the transfer of energy by a wave to the medium through which it travels
9. a disturbance that transfers energy from one place to another without transferring matter.
11. occurs when waves that overlap combine, forming a new wave
12. When a wave is reflected from a surface the angle of reflection is equal to the angle of incidence
16. The maximum distance that the wave moves from its rest position
18. The highest point on a transverse wave
