Waves

5. / the wave changes direction because it bends around an object.
7. / the distance between two crests or two troughs of a wave.
8. / something waves travel through.
9. waves / move through air because a vibrating source produces.
11. / combination of two overlapping waves.
13. / the time for a particle on a medium to make one complete vibrational cycle.
14. / the lowest point on a wave.
16. / the bouncing back of a wave that strikes the boundary between two media.
17. / places that appear to be stationary dot on the midpoint.

1. / a wave that has properties of a transverse wave but doesn't need a medium throught which to travel.
2. / the highest point on a wave.
3. / an area of high pressure of a wave.
4. / a wave in which the particles of the medium are displaced in a direction perpendicular to the direction of energy transport.
6. / how often the particles of the medium vibrate when a wave passes through the medium.
10. / a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport.
12. / an area of low pressure on a wave.
15. / the change indirection of a wave as it crosses the boundary between two mega in which the wave travels at different speeds.
