Waves

3. where the particles of the medium are close together.
8. transverse waves that carry energy without a medium
14. Horizontal distance between the crests or between the troughs of two adjacent waves
15. Wave that the particles move backwards and forwards in the same direction as the energy transfer
16. The bouncing back of a wave when it hits a surface through which it cannot pass.
17. the place where something begins
18. to move from one place to another
20. Anything that has mass and takes up space
22. The bending of a wave as it passes at an angle from one medium to another
23. the height of a wave's crest
24. lines that never intersect
25. a part in a longitudinal wave where the particles are spread apart

1. the highest point of a transverse wave
2. Occurs when an object causes a wave to change direction and bend around it
4. A wave that requires a medium through which to travel
5. the number of complete wavelengths that pass a point in a given time
6. the lowest point of a transverse wave
7. Going straight across from side to side
9. the ability to do work
10. the speed at which a wave travels through a medium
11. A disturbance that transfers energy from place to place
12. The position in the wave where particles are not disturbed; half way between the crest and trough.
13. at an angle of 90°; a right angle
19. Material/matter through which a wave travels
21. straight up and down
