Waves 2

3. A wave that can travel only through matter
5. When a wave is reflected from a surface the angle of reflection is equal to the angle of incidence
8. The region of a longitudinal wave where the particles in the medium are closest together
11. A wave in which the disturbance is perpendicular to the direction the wave travels.
12. The passage of light through an object
16. the change in a direction of a wave that occurs when the wave changes speed when moving from one medium to the other
18. makes the particles in a medium move parallel to the direction that the wave travels.
20. A wave that can travel through empty space and matter

1. the distance from one wave point to another
2. a material in which a wave travels
4. the transfer of energy by a wave to the medium through which it travels
6. The highest point on a transverse wave
7. The region of a longitudinal wave where particles are farthest apart
9. Change in direction of a wave when it travels by the edge of an object or through an opening
10. a disturbance that transfers energy from one place to another without transferring matter.
13. The bouncing of a wave off an object
14. occurs when waves that overlap combine, forming a new wave
15. The number of wavelengths by a point each second
17. The maximum distance that the wave moves from its rest position
19. The lowest point in a transverse wave
