Waves

6. spectrum the change in frequency of a wave (like sound or light) observed by an observer who is moving relative to the wave's source
8. When two or more waves cross at a point, the displacement at that point is equal to the sum of the displacements of the individual waves
10. where particles are pushed together in a longitudinal wave
11. The amount of energy carried by a wave
14. a wave vibrating in the direction of propagation
16. a wave vibrating at right angles in the direction it’s traveling
17. when an object causes a wave to change direction and bend around it
19. Highest point of a transverse wave
20. where particles are spread apart in a longitudinal wave

1. Does not allow transmission of light waves
2. The number of waves that pass a given point in one second
3. an electromagnetic wave, like light, that passes through an object without being significantly absorbed or reflected.
4. shift the change in frequency of a wave (like sound or light) observed by an observer who is moving relative to the wave's source
5. when a wave strikes an object and goes into it
7. Lowest points of a transverse wave
9. light may pass through that material but images on the other side of that material are not clearly visible
12. Matter through which a wave travels through
13. The distance between one point on a wave and the nearest point just like it
15. The bending of waves caused by a change in its speed as it moves from one medium through another
18. The change of direction of propagation of a wave when it meets a boundary
