Waves Lesson 1 and 2

1. matter a wave travels through
3. distance between the highest crest and the resting position
4. the bouncing back of an object or a wave when it hits a surface through which it cannot pass
6. an example is space, an area a wave cannot travel through
7. the bending or spreading of waves as they move around a barrier or pass through an opening
10. going from one medium to another
11. wave that travels in the same direction as the vibrations that produce it
14. the bending of waves due to a change in speed
18. a wave that appears to stand in one place

2. a type of energy
5. moves through some type of matter
8. the number of times a wave repeats in a given amount of time
9. any disturbance that transfers energy from place to place
12. transfer of energy from a wave to a material that it encounters
13. waves that travel perpendicular (at right angles) to the direction of the source's motion
15. an increase
16. determined by the distance a wave travels before it starts to repeat
17. interaction between waves that meet
