Waves

5. 2 or more waves arrive at the same point at the same time and combine to make a single wave
7. the medium moves at right angles in the direction of the wave
9. A disturbance that carries energy from one place to another is called a
14. wave that requires no medium and travels in between particles
16. particles are close together
17. height of a wavelength measured from crest to trough

1. number of waves that go past a point in one secon
2. distance between one point on a wave and the exact same point on the next wave
3. wave that requires a medium to travel from one particle to the next particle of a medium
4. particles are spread apart
6. takes place when a wave passes from one medium to another at an angle
8. results when a wave passes through a hole or a barrier and spreads out
10. the medium moves back and forth in the same direction as the wave
11. material in which a wave travels through
12. when a wave hits an obhect it cannot pass through or reaches the boundar of a medium
13. phenomenon in whcih there is a change in the frequency due to motion of the wave source or wave observer
15. space where there is no matter
