Waves

3. More dense region of a longitudinal wave.
4. Matter through which a wave travels.
6. Made by vibrating electric charges.
10. Process by which an object is made to vibrate by absorbing energy at its natural frequencies.
11. High point of a transverse wave.
12. Bending of a wave around an object.
13. Particles in the medium move back and forth at right angles to the direction that the wave travels.
16. Less-dense region of a longitudinal wave.
18. Measure of the size of the disturbance from a wave.
19. Locations where the interfering waves always cancel.
20. Special type of wave pattern that forms when waves equal in wavelength and ampliture but travel in opposite directions continuously interfere with each other.

1. Distance between one point on a wave and the nearest poit just like it.
2. The process of two or more waves overlapping and combining to form a new wave.
5. Waves that can only travel through air.
7. Matter in the medium nove back and forth along the same direction that the wave travels.
8. Low point of a transverse wave.
9. Amount of time it takes one wavelength to pass a point.
14. Bending of a wave caused by change in its speed as it travels from one medium to another.
15. A repeating disturbance that transfers energy through matter or space.
17. Number of wavelengths that pass a fixed point each second.
