Chapter 15

2. The regions of a longitudinal wave where the particles are farthest apart
5. A wave that can travel only through matter
8. when a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
11. A wave in which the disturbance is perpendicular to the direction the wave travels
13. A wave that makes the particles in a medium move parallel to the direction that the wave travels
14. A material in which a wave travels
16. The lowest points on a transverse wave
18. the bouncing of a wave off a surface
20. the change of a wave when it travels by the edge of an object or through an opening

1. occurs when waves that overlap combine forming a new wave
3. the change in direction of a wave that occurs as the wave changes speed when moving from one medium to another
4. the distance from one point on a wave to the same point on the next wave
6. The highest point on a transverse wave
7. the maximum distance that the wave moves from its rest position
9. the transfer of energy by a wave to the medium through which it travels
10. A disturbance that transfers energy from one place to another without transferring matter.
12. A wave that can travel through empty space and through matter
15. the number of wavelengths that pass by a point each second
17. The regions of a longitudinal wave where the particles in the medium are closest together
19. the passage of light through an object
