Waves

2. Bending of a wave around an object.
5. Low point of a transverse wave.
9. Made by vibrating electric charges.
13. The process of two or more waves overlapping and combining to form a new wave.
15. More dense region of a longitudinal wave.
18. Special type of wave pattern that forms when waves equal in wavelength and ampliture but travel in opposite directions continuously interfere with each other.
19. Measure of the size of the disturbance from a wave.

1. Matter in the medium nove back and forth along the same direction that the wave travels.
3. Particles in the medium move back and forth at right angles to the direction that the wave travels.
4. Process by which an object is made to vibrate by absorbing energy at its natural frequencies.
6. A repeating disturbance that transfers energy through matter or space.
7. Waves that can only travel through air.
8. Less-dense region of a longitudinal wave.
10. High point of a transverse wave.
11. Locations where the interfering waves always cancel.
12. Number of wavelengths that pass a fixed point each second.
14. Matter through which a wave travels.
16. Bending of a wave caused by change in its speed as it travels from one medium to another.
17. Distance between one point on a wave and the nearest poit just like it.
20. Amount of time it takes one wavelength to pass a point.
