Wave properties

2. the transfer of energy by a wave to the medium through which it travels.
4. the parts of a longitudinal wave where the particles are farthest apart.
6. a wave that can only travel through matter.
8. the lowest points on a transverse wave.
9. the bouncing of a wave off a surface.
11. a material in which a wave travels.
12. when a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
14. a wave in which the disturbance is perpendicular to the direction the wave travels.
15. the parts of a longitudinal wave where the particles are closest together.
18. a wave in which the particles move parallel to the direction the wave travels.
20. the change in direction of a wave that occurs as the wave changes speed when moving from one medium to another.

1. the change in direction of a wave when it travels by the edge of an object or through an opening.
3. the passage of light through an object.
5. a disturbance that transfers energy from one place to another.
7. a wave that can travel through empty space and through matter.
10. when waves that overlap combine, forming a new wave.
13. the highest point on a transverse wave.
16. the distance from one point on a wave to the same point on the next wave.
17. the number of wavelengths that pass by a point each second.
19. the maximum distance that the waves move from their rest position.
