Waves

3. the bending of a wave as it moves around a obstacle or passes through a narrow opening.
6. the bending of a wave as it enters a new medium at an angle
10. the complete number of cycles in a given time
11. the lowest point of a wave below the rest position
12. the maximum displacement of the medium from its rest position
14. when two or more waves combine to produce a wave with a smaller displacement.
15. an are where the particles in a medium are spaced close together
16. when two or more waves overlap and combing together
19. the distance between a point on one wave and the same pint on the next cycle of the wave

1. material through which waves travel
2. when two or more waves combine to produce a wave with a large displacement
4. a wave in which the vibration of the medium is parallel to the direction the wave travels
5. an area where the particles in a medium are spread out
7. a wave that causes the medium to vibrate at right angles to the direction in which the wave travels
8. occurs when a wave bounces off a surface that it cannot pass through
9. a wave that travels along a surface separating two media
13. carries matter from one place to another
17. the highest point of a wave above the rest position
18. the time required for one cycle
