Waves

3. perpendicular to the direction of the wave
4. highest point of a wave
9. When an object causes a wave to change direction and bend around it
11. the number of wavelengths that pass a fixed point each second
12. repeating disturbances or movement that transfers energy through matter or space
16. particles in a longitudinal wave are closest together
17. when light bounces off a surface
19. the size of a disturbance from a wave
20. parallel with direction

1. a place in a wave where the molecules are far apart
2. when two or more waves overlap and combine to form a new wave
5. process by which an object is made to vibrate by absorbing energy at its natural frequencies
6. Wave bends due to change of speed
7. lowest point of a wave
8. the distance between one point on a wave and the nearest point just like it
10. waves that can travel through earth and along the surface
13. The amount of time it takes one wavelength to pass a point
14. the matter through which mechanical waves travel
15. What type of waves can be either transverse or compressional
18. Forms when waves equal in wavelength and amplitude
